Sorry...I am not the one who was saying "where did Jesus say"

that was from the fundamentalist side of the church (port side).

Catholics aren't sola scripturalists!

There is no doubt that Our Lord prayed for unity...and Our Lord didn't half pray that.

He wants unity in belief and unity in doing His will.  He doesn't want multiple "belief systems". 

Unity doesn't equal uniformity, but it also doesn't mean Babel.
