Faith-confidence in what we hope for (Hebrews 11)
Christendom is a word that by the 14thc. was used by Mediaevals to designate their Christian world. It occurs in Old English.
When people read the scriptures and a word is intentionally substituted for another because of tradition by the editors, then yes -- it is deception. Even if there is an explanation in small print, many people go to church and don't read their Bibles much anyway. Or know that point. Of course when Jesus offered what is called the "Lord's prayer," he said (in many versions), "Hallowed by thy NAME." He didn't say don't use the name. I could go further but I won't out of respect.This is your interpretation. Your statement that it "does not mean" something is as persuasive to me as my statement that "it does mean" would be to you. Your calling something lying or deception is likewise just your opinion and not really useful.
Also, to deliberately leave out God's name as Moses wrote it and others wrote it in the early documents, is a sin.
In some English Bibles they are honest enough to have a brief explanation as to the name at Psalm 83:18, and some Bibles do have the name written out.
