Leaving the vowel out of God’s name is usually done to show respect. Using a lower case for Christianity is usually done to show disrespect.
Is Christ God, and thus deserving of respect, or is Christ not even a title deserving of respect? What point were you trying to make with your headline?
I’ll try to cite an answer for you another day. But we very strictly only believe in The One G-d, and we try to avoid displaying names of any others. It has to do with our first Law (for Gentiles and everyone).
