I don't doubt that. But when you talk about Catholic doctrine, you almost immediately construct a straw man, which shows that you don't understand it.
If you believed that Christ has justified His flock, you would not seek absolution from other men,
That is a non sequitur. You are using your Calvinistic conception of justification, and imposing it on Catholic theology. Moreover, Christ Himself is the one who told His Apostles in John 20:21, "If you forgive the sins of any, their sins have been forgiven them; if you retain the sin of any, they have been retained." Christ is referring to the authority of the keys of the kingdom of heaven. The merits of Christ's work come to us through the Church. That is why Christ's work on the cross is not incompatible with seeking absolution from the Magisterium according to John 20:21.
-A8
Give it up, A8. Recognize the liberty Christ has given you through His one-time sacrifice which has been offered and accepted by God for all the sins of Christ's flock.
By the which will we are sanctified through the offering of the body of Jesus Christ once for all. And every priest standeth daily ministering and offering oftentimes the same sacrifices, which can never take away sins: But this man, after he had offered one sacrifice for sins for ever, sat down on the right hand of God; From henceforth expecting till his enemies be made his footstool. For by one offering he hath perfected for ever them that are sanctified." -- Hebrews 10:9-14"Then said he, Lo, I come to do thy will, O God. He taketh away the first, that he may establish the second.
