These Christian scholars reject the Trinity and you (as a Muslim) will say that us Christians seperate on the issue. But when someone blows up a building in the name of the Allah of Islam what will you say then about your religion? You will say that they are not really following the teachings of Islam. Now apply that saying to some of the people who call themselves Christians and you will have my reply to your quote, listing those Christian scholars that need proof of the Trinity.
Wooooooooooo!!! Alpha we are not talking here about liberal Christians, we are talking here about:
The Catholic Encyclopedia
The New Catholic Encyclopedia
Etc............
