I'm not going to keep going around and around on this...your OWN SOURCE you quote even claims Christians use Isa. Case closed. I'd repent for judging RW's heart.
Oh, good grief. You are just reaching here. I quoted the same passage you just did, except I did it in context. Do you miss the part where it says that 99% of arabic christians use Yasu. Did you also miss the part where they use Esa in a very specific situation? Did you miss the part where I referred you to another thread where we had a discussion about this practice and how it really isn't a good thing to do?
You own words were, "While many Christians may still use Yasu, it is more of a matter of preference like KJVO." I've provided proof that it is not just a matter of preference. I've provided proof that arabic christians use Yasu exclusively, except in one very specific case. Where's the proof for your statement? You've also stated, "Muslims use Yasu in the Q'ran as well". Where is your proof for that? Please show me where in the Q'ran that Yasu is used?
Stop apologizing for Warren. He used the name Isa to try and include Muslims in his little speech. He did it specifically because he was trying to convey a message that we all worship the same God. It follows his pattern of inclusiveness.
