What you call the church is not the Church Jesus started - it is a counterfeit. Jesus who is the Head of His Church and it is based on who He is - THE WORD who became flesh. Thou art the Messiah, the Son of the living God.
Catholicism is based on man made teachings and man is their head. They deny the Trinity as they insert 'man' - where Jesus should be. With each pope they are saying he is the - the Son of the living God. There will be plenty of gnashing of teeth when all is said and done. Then they have idolatry to answer for, also. And the list goes on.
But of course we will have to take your word for it because you are an expert on Catholic theology, right? Please let me know where you learned this since I personally have never heard that before.
