Jesus gave himself to us before there was a church. “He who believes in me shall not perish”.
But that is not what Scripture says:
And I say also unto thee, That thou art Peter, and upon this rock I will build my church; and the gates of hell shall not prevail against it. Mat 6:18
Christ established His Church.
And the Church is the 'pillar and foundation of faith'
But if I tarry long, that thou mayest know how thou oughtest to behave thyself in the house of God, which is the church of the living God, the pillar and foundation of the truth. 1Tim 3:15
Jesus established the Catholic Church on the Apostles as he breathed on them on Sunday monring when he was cooking breakfast for them.
“Receive the Holy Spirit, whose sins you shall forgive, they are forgiven them; whose sins you shall retain, they are retained.”
Surely that is in your Bible too? Correct?
