My hope is the Father.
My refuge is the Son.
My shelter is the Holy Spirit.
O Holy Trinity, glory to you.
– St. Ioannikos, 9th century

Pardon my ignorance, but aren’t the Father and Spirit non-human-looking-spirit beings?

Tejas, thanks for your question. This is the traditional icon of the Blessed Trinity. The persons shown in the icon are the Father, Son, and Holy Spirit. However, the icon is not attempting to depict them in their divine personages. The icon is based on the three men, considered angels, who visited Abraham (Genesis 18:1-9). They are seen as prefiguring of the Holy Trinity. I hope this answers your question.
Easter joy and blessings. Christ is risen!
Mike+
