>Now I say to you that you are Peter (which means ‘rock’), and upon this rock I will build my church, and all the powers of hell will not conquer it.Jesus Christ establishes His (Holy and Catholic) Church and Peter, who himself was not without sin, is the foundation (rock) from which it will be built off of. This starts the Catholic Church, which continues, with the grace of God, to this day.
To say Catholics aren't Christian is ludicrous and a radical statement fit for a member of the synagogue of Satan (which Martin Luther and all those who followed in his footsteps became a member of when he rejected Christ's Church and decided that his word was better than Jesus Christ's).
>Priests can't marry and must remain celibate.Once upon a time they could but celibacy was made a church discipline
