ΟΨ
That's OPS, Greek for Eye. If you use the Omicron as a cookie-cutter on the Psi, you end up with what is virtually the Opus Dei logo (upside-down).
OPOS is also Greek for Eye, which adds a whole 'nother layer of meaning to Opus Dei ...
Is it the Work of God or the Eye of G-d?
That is the question.
I'm sure JezusDeKoning will be able to answer it for us.
