This is the very reason that Christianity has survived 2,000 years. The alternative would be the fractious environment in which every heresy gains traction, in which YOPIS reigns, in which every milk maid and farm hand is their own pope and 30,000 denominations is just a start.
I thank God for the Church and it's Magisterium that guides and teaches the Truth.
The Council of Trent flatly rejected and contradict the Council of Orange. The Church has changed the doctrine of the early fathers to such a point it really no longer resembles the early church nor shares a Christian heritage. It has abandon the concept of grace, it has distorted the atonement, it has changed the First Commandment to suit its actions, and it has instituted theology that never was discussed in the holy word of God.
Yet you "thank God" that the "Church" "guides and teaches the Truth". I suppose you can ponder that comment as you bow down and pray to the statue of Mary.
