The Catholic Church is the one authorized teacher of divine truth and I'm not talking about the impostor Church that many believe to be the Roman Catholic Church which is in fact not Catholic but a different religion occupying the Vatican and deceiving billions of people.
There are tons of protestant arguments against the Catholic Church and they are all based on false interpretations of the bible and lies. I can't think of any protestant arguments that hold any real weight. They believe in sola scripture which is a self refuting doctrine. Every protestant sect believes he has the true interpretation of the Christian faith, but how can that be when there are thousands of protestant sects that contradict each other. Some so far as to reject the Holy Trinity. Even the so called "Orthodox" Church doesn't have an real weighty arguments. All the eastern Church schismatics before they separated from Rome believed in Rome's authority. Same with the protestants. Luther appealed to Rome. Obviously today, we are dealing with a much different and unprecedent crisis where the Church is in eclipse (Our Lady of La Salette predicted) and no longer teaches the Catholic faith, but a perverted faith and the real Church is few and sparse in number but still holds to the undefiled truth, the Catholic faith.
There is only one Catholic Church. Christ instituted his priesthood.
"He that hears you hears me: and he that despises you despises meβ (John 10:16)
"Do this for a commemoration of me" (Luke 22:24)
"Receive the Holy Ghost; who soever's sins you forgive they are forgiven, who soever's sins you retain, they are retained" (20:21-23).
"Neglect not the grace that is in thee , which was given thee by prophecy, with imposition of the hands of priesthood" (I Tim. 4:14).
