When you agree with others it should be with your mind, fully, as an individual rather it be with what your Church teaches you or with another individual.So you do not believe that Christ set up a Church? To teach?
Yes, but in the context that they are people and fallible. Therefore it is up to we, ourselves, to make sure by searching and being well acquitted with Scripture that what they are teaching us is true.
No, Jesus did not set up a Church, to teach...Jesus set up many churches...And Jesus knew there would be heresies...And Jesus allowed the heresies to exist, within the churches...To exist so that we could see their errors...Thus, the Catholic religion with it's single Church...
