MuslimGladiator, we welcome respectful debates, however just because you cannot respond to posts made by others is no reason to resort to personal attacks.
I doubt any Christian who has any knowledge of Catholicism does not know what transubstantiation means. Catholicism is wrong when they teach that the bread and wine miraculously transform into the real body and blood of Jesus Christ, which Jesus clearly explained in John 6:61-65.
Now are you willing to discuss Christianity and Islam or is your only agenda to assume that Catholicism represents all Christians?
Now, if anyone has shown a lack of maturity it is you by not responding to questions put to you.
