As you have indicated that you do not accept all of the teachings of Jesus Christ and His Catholic Church, I accept His teachings.
Just as Judas was replaced by another apostle, Matthias.
“Then they gave lots to them, and the lot fell upon Matthias, and he was counted with the eleven apostles.” Acts1
The Church continued through the successors to the Apostles who were ordained and continued the mission of Jesus to Preach and Baptize all nations.
During his public life Jesus not only forgave sins, but also made plain the effect of this forgiveness: he reintegrated forgiven sinners into the community of the People of God from which sin had alienated or even excluded them. A remarkable sign of this is the fact that Jesus receives sinners at his table, a gesture that expresses in an astonishing way both Gods forgiveness and the return to the bosom of the People of God. (CCC 1443)
In imparting to his apostles his own power to forgive sins, the Lord also gives them the authority to reconcile sinners with the Church. This ecclesial dimension of their task is expressed most notably in Christs solemn words to Simon Peter: “I will give you the keys of the kingdom of heaven, and whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven.” The office of binding and loosing which was given to Peter was also assigned to the college of the apostles united to its head. (CCC 1444)
The words bind and loose mean: Whomever you exclude from your communion, will be excluded from communion with God; whomever you receive anew into your communion, God will welcome back into his. Reconciliation with the Church is inseparable from reconciliation with God. (CCC 1445)
Thanks for telling what Rome has decided.
We implore you on Christ's behalf: Be reconciled to God.
Church is not mentioned in either!
