They describe in detail to us every day what they believe. The Catholic Church also posts all of their beliefs online. I don't have to guess or wonder. As the Catholic Church states. You must submit you intellect and will to the magisterium. I submit my intellect and will to Christ and the Holy Spirit.
I must be a lousy Catholic because I don't submit my will and intellect to the magisterium. Of course I listen and pray to the Holy Spirit to understand the teachings of dogma put forth by the magisterium whom I believe use the guidance of tradition, Holy Scripture, and prayers to the Father, Son, and Holy Spirit. It was probably the early magisterium that wrote the Apostles Creed. Magisterium are teachers of the faith aren't you in some respects a teacher of the Faith to others.
You must know your wasting your time in trying to have me accept the all same beliefs as you. I like being a Catholic, a Knights of Columbus etc.. and trying my best to do the Will of God by keeping the Great Commandment. I wouldn't try to change you by trying to tear down your religious beliefs. I think we have enough in common to let things rest in that regard.
Let's work together to promote respect for God, life, and liberty, seems to me that's what Americans need to focus on.
