Flag of Orthodoxia

Description
A square blood-red flag with a centered gold cross touching all four sides of the flag. In the four corners in gold are the inscriptions 'ΙϹ', 'ΧϹ', 'ΝΙ' and 'ΚΑ', ordered left-to-right then top-to-bottom.

Current specifics
The lines of the cross are one-tenth the width of the flag.
Blood-red: #660000
Gold: #FFC000 (Amber)
Font: Athonite

Rationale
The Christogram 'ΙϹ ΧϹ ΝΙΚΑ' is widely used across Orthodox Christianity. The colors are a variation of the red and gold found in Byzantine flags, blood-red and gold, a combination widely found within iconography.
The previously used region flag with the double-headed eagle is really mostly the flag/symbol of the Ecumenical Patriarchate and Mount Athos nowadays, and considered was the three-bar cross, but it's mostly Slavic.
