Sacrificing Our Certitude – A Sermon On Genesis 22:1-14

Published by

“God tested Abraham.” (Genesis 22:1-14)

So what do you think? Was Abraham being faithful when he “reached out his hand and took the knife to kill his son”? Did he pass the test?

The usual interpretation is yes. He proved that he feared God. He proved his faithfulness. Abraham passed the test.

Not The Usual Interpretation

But I’m not so sure. I struggle with this story. What about you? I don’t think I’m the only one. I can’t make sense of it. I cannot resolve it for you or myself. I don’t think it’s as simple as hearing and obeying the voice of God. It never is. After all, more than one murder defendant has said they heard the voice of God tell them to kill another – and no one believes that. The juries don’t. I don’t. Do you? 

I wonder if Abraham failed the test and that’s why the angel intervened at the last minute to stop the killing. Despite my struggle with this story or maybe because of that struggle, I still think the story has a profound and urgent lesson for us today. 

Several years ago I asked my friend Rabbi Joe about this story. “How do you all make sense of it?” I asked. “What do you do with it?” He said, “I ignore it. That’s not who God is.” 

Then he went on to talk about midrashim, the stories and commentaries that rabbis throughout the centuries have written in an attempt to understand, explain, and resolve this text. Apparently, Judaism struggles with it as much as do you and I.

Let me add one thing here. I refuse to accept the worn out and heretical argument that there are two different Gods, an Old Testament God of law and violence and a New Testament God of grace and peace. I hope you will refuse that as well. The God of Abraham is also the God of Jesus is also the God of you and me.

I agree with Rabbi Joe, that’s not who God is, but it sure seems to be who we are as people. The late Jonathan Sacks, former Chief Rabbi of Great Britain said, “We are never more willing to kill than when we do so in the name of God.”

Abraham’s Certitude

That’s not faithfulness. That’s certitude. What if Abraham is acting out of certitude and not faithfulness? There’s a fine line between the two. And sometimes we use God to give credibility to our certitude.

Certitude is my subjective absolute conviction about something. There is no self-reflection, no conversation with others, and certainly no consideration that I might be mistaken or wrong. There is only one way, my way. I know more and better than anyone else. If I think it or believe it then that settles it. Certitude closes my eyes, ears, and heart.

I wonder if certitude is why Abraham never objects, questions, or argues with God. Can you imagine keeping quiet in that situation? How can Abraham who negotiated with God on behalf of Sodom and Gomorrah not speak up on behalf of his own son, his only son Isaac, whom he loves?

Isn’t it interesting that Abraham never told Sarah about what God had told him to do? Do you think she might have had something to say about that? Do you think she would have shared his certitude? Offered to pack his lunch and help him get ready? Maybe Abraham didn’t want to hear what Sarah would’ve had to say. Certitude usually only wants to hear its own voice. 

I can easily imagine that on the way home Abraham said to Isaac, “Let’s just keep this between us. What happened on the mountain stays on the mountain. There’s no need to tell your mom about what happened up there.”

Neither did Abraham tell the two young men he took with him. Instead, he lied to them about his plan. “Stay here with the donkey; the boy and I will go over there; we will worship, and then we will come back to you.” Maybe he was lying to himself too. Maybe that’s a way we keep our certitude. 

And it’s no surprise that Abraham didn’t tell Isaac. To speak it out loud would have called everything into question. Silence and secrecy are the co-conspirators of certitude. 

I don’t say any of this as a judgment or criticism of Abraham, but in recognition that I too have my certitudes. Maybe you do too. What are the certitudes you and I are living with today? 

Our Certitude

What if the real test of Abraham, isn’t whether he would sacrifice his son Isaac, but whether he will sacrifice his certitude? What would it be like and take for you and me to sacrifice and let go of our certitudes? Here’s why I think that mattress. 

Every day we see and live with the consequences of certitude, our own or another’s. It seems to me that certitude is a primary cause of death, injustice, and violence in our lives and world today – whether in our personal relationships or our national and global ones.

With certitude we bomb the world to pieces absolutely convinced that we are making peace. In our certitude we say that some lives matter more than others, some are welcome and others are not, some have dignity but others don’t. Certitude polarizes our politics. It prefers monologues to dialogue. It speaks but doesn’t listen. It’s at the heart of our judgments about and ridicule of others. 

Certitude leaves us isolated and without need of others. Certitude hardens our heart and narrows our vision. It disconnects us from something larger than and beyond ourselves. 

Maybe that angelic intervention on the mountain saved not only Isaac but also Abraham from Abraham’s certitude. Maybe we all need to be saved from our certitude. 

Did you know that after the near sacrifice of Isaac holy scripture never records God as having spoken to Abraham again? 

Faithfulness Without Certitude

Maybe Abraham left his certitude on the mountain that day. What if that was the beginning Abraham’s faith?

Faithfulness without certitude. What do you think? Can you do that? And what would that look like in your life.

Faithfulness without certitude. It just might give God something to work with. We just might discover, as did Abraham, that “the Lord will provide.”

    This is so what I need to wrap my mind around this morning. We still have our home up for sale but the market is dead. It is a long holding pattern. I need to know that God will provide. “And in the end, all shall be well”.

    1. Michael K. Marsh Avatar

      Pat, thanks for Julian’s reminder. It fits perfectly with Abraham’s “The Lord will provide.” I hope that promise soon becomes a reality for you all.

      Peace be with you,
      Mike

    Just thinking about abandoning certitude feels like a burden is lifted. Like wonder & awe have returned. I feel lighter. Thank you.

      I really appreciate your insight that certitude is a heavy burden to carry. Thank you for that.

      God’s peace be with you,

    As a cradle Catholic my life has been overwhelmingly filled with certitude. As a child the message is we must convey everyone we know to Catholicism and to avoid spending time with those non Catholic kids. As a child I never understood this but there sure were a lot of school heard fights between our Catholic school and the non Catholic school just down the street. That is when I had my first lesson about maybe, just maybe we were not supposed to do what we were commanded. Fortunately over decades and with growing older, now in my 80’s I have very little certitude with the exception of knowing I am absolutely loved by God, the got who created and has sustained this long life. It is through that growing awareness and the experience with “the other” that I have been much more aware and in awe of all that exists, including other ways of believing in God in their unique ways and it certainly isn’t just “Catholics” that our God loves. The only bit of certainty that remains important is to love God with my whole mind, heart and being and to love my neighbour which includes “all” as myself. As a caveat that does not mean I have to approve behaviour that causes harm. Thank you for this reminder about questioning certitude.

      What lovely experiences and insights. Thank you for sharing them Shirley. I hear a sense of freedom and expansiveness in what you describe – the very opposite of certitude.

      God’s peace and blessings be with you,

    Thank you for redeeming this complicated passage for me. Seeing it and my own certitude in a new way.

    1. Michael K. Marsh Avatar

      I’m glad the sermon offered a new way of seeing the text and our certitude. Thank you for your comment and for reading my blog.

      God’s peace be with you,

    Thanks, Mike. I appreciated the glimpses of how we protect our certainty from the input/wisdom/disruption of others. And of how destructive that winds up being. I know in stress I can hunker down. I’m hearing this as a prompt to risk staying connected and open despite uncertainty.

    1. Michael K. Marsh Avatar

      Ann, I like the image of, and recognize in myself, hunkering down as a form certitude. So, as you say, maybe risk and openness are the antidotes – a medicine that often does not taste good!

      Peace be with you,
      Mike

    Wow. I’m with you and Rabbi Joe. I see others with the certitude you’ve discussed here and don’t understand it. Thanks, Mike.

    1. Michael K. Marsh Avatar

      I don’t understand it either – especially when I see it in myself!

      Peace be with you,

    I always feel that those who are proud of their certainty, and think that they have all the answers, have not yet found half the questions.

    1. Michael K. Marsh Avatar

      James, that’s a great insight. So maybe the work is less about having certitude and more about asking better questions. Thank you for your comment.

      Peace be with you,

    Dear, dear Mike,
    Yes! Certitude is, for sure, often a dangerous and pernicious stance! I, too, have struggled with the Abraham who was willing to sacrifice his son (at what he believed was God’s command) AND the sermons’ interpretations on this subject! I struggle with certitude as it is spoken from our government! I find that certitude doesn’t help me most of the time! So, I am saying, “thank you” for your help in understanding. I, too, am often being invited to sacrifice my certitude.
    Thank you, and blessings to you,
    Jan

    1. Michael K. Marsh Avatar

      Thank you Jan. I recognize myself in what you say. I suspect the sacrifice of our certitude is more an ongoing practice than an achievement.

      Peace be with you,
      Mike

    From Albert Schweitzer – My Life and Thought – 1931
    “The essential element in Christianity as it was preached by Jesus and as it is comprehended by thought, is this, that it is only through love that we can attain to communion with God. All living knowledge of God rests upon this foundation: that we experience Him in our lives as Will-¬to-Love.
    “Anyone who has recognized that the idea of Love is the spiritual beam of light which reaches us from the Infinite, ceases to demand from religion that it shall offer him complete knowledge of the supra-sensible. He ponders, indeed, on the great questions … but he is able to leave these questions on one side, however painful it may be to give up all hope of answers to them. In the knowledge of spiritual existence in God through love he possesses the one thing needful.”
