Truly amazing how the same people moan about Catholic doctrines etc. People who are really uneducated in Catholicism.
How would Sola Scripture believers have managed before the Bible was assembled?
Also, many, many, many, many people could not read or write so how would they have been able to use sola scripture?
Also, people complain about Catholic Doctrine but remember it was Catholic people who chose and assembled the Bible with the Holy Spirit guiding them!
Trying to convince a Catholic that the doctrine is unbiblical is worthless as we can come up with scripture as has been shown again and again but it is always either ignored or pushed to one side!
Praying to Mary, to the Saints is God given as far as a Catholic is concerned. Many miracles have happened to prove the power of these prayers. Many documented miracles of people praying to Mary or certain Saints. God would not do these miracles if they were not just and worthy.
As I said before. God works in mysterious ways. God works outside of scripture too. He is not only accessible just in scripture.
