Dear JordanWoods, one can never “convince” someone to love them. The Catholic faith is just that - FAITH. God calls every human being into a personal relationship with Him. This cannot happen through the convincing of others. Jesus proves His infinite love for us by becoming one of us and taking on sin for our sake. Since God is the furthest possible thing from sin, this was the sacrifice of all sacrifices, and it was done out of love for us. Another thing Christ did while He walked among us was to establish His Church (His Bride) and the sacraments which supply the graces necessary for our journey. Since the Catholic Church has apostolic succession which can be traced all the way back to Peter, our first Pope, then it is the one and only Church which was established by Christ, and is, therefore, the fullness of the truth. Since Christ Himself is truth, that it also what His Church is - the fullness of the truth. And although other denominations have some truth, they do not have it all. Only the Catholic Church has it all.
So you should enter the Church out of love for God and His truth. This truth is something you must seek out yourself and be convinced by your own beliefs. The normal means would be by prayer. Ask God to guide you, fill you with His Holy Spirit, and enlighten you to the truth. How on earth would someone else (most especially an anonymous person on a web forum) be able to convince you of something so important?
