I have a question...where did a tax collector and a few fishermen get their degree? They listened directly to the Master, our Lord Jesus Christ. Then they wrote down His words so we too could get the words and actions of Christ directly.
How many times in the NT do we see passages as this one?:
Acts 4:
13 Now when they saw the boldness of Peter and John, and perceived that they were uneducated and untrained men, they marveled. And they realized that they had been with Jesus.
Those men were taught by Christ Himself. They passed the faith on to other men when they formed the Catholic Church, the Pillar and Foundation of Truth.
These men pased it on to others who formed seminaries to insure that this truth was passed on faithfully.
seeing as how no protestant church can draw a lineage back to these men, the question remains.
