Because Jesus did not found the corrupt and immoral organization known as the Catholic church.
His commands about how to organize and run a church are found throughout Paul's epistles and when Roman Catholicism starts to work according to that, then it might have the right to call itself a church.
Until then, it's nothing more than than a homosexual infiltrated pedo rig that fails to obey the very Scripture it claims to have written.
Hence, it has no authority ov3er the lives of any believer in Christ. That claim is just a power grab by Catholicism.
Your comment: “Because Jesus did not found the corrupt and immoral organization known as the Catholic church.”
Shows a lack of knowledge of history and non belief in the Truth of Jesus.
The Catholic Church welcomes all sinners as the father (god) welcomed the prodigal son. The Church recognizes the difference from the sin and person made in the image of God that has the opportunity to repent.
The Catholic Church and Jesus call us to change away from sin and confess our sins in the Sacrament of Reconciliation.
