Re: Jesus, not the first
Migagawe, your wording is interesting. You said "to prove Allah wrong." Allah is simply the arabic word for God, not some sort of opposing messiah. You also said "what separates Christians from Catholics." Catholics are Christians. You're either assuming your own version of Christianity is the only one that opposes Catholicism, or you forgot to include the word "other" before "Christians." Careful with that.
