Ryan, I appreciate your willingness to do these youtube lectures. For about 2 years, I've been trying to find a way to study church history without having to buy a million books. This has been greatly helpful. Bless you, sir. I've watched this Luther series and the Church History I in their entirety.

Another great informative video. Thanks. I was hoping to find out if Luther ever changed his mind about transubstantiation, but I guess I'll have to wait and hopefully find out in one of the next videos. The argument Zwingli used that Jesus also said I am the door, I am the true vine, light of the world, etc. happens to be the same argument that I've often used myself. Also, as a former catholic, John 6:53-58 (he who eats my flesh...) is read at mass on more occasions than any other verses of scripture. But they always cut it off before Jesus is actually explaining what he meant about these words when he is speaking to the disciples alone in verses 61- 63. In addition, the priest will just quote the scripture with no other information so that many people assume that Jesus said these words at the last supper, instead of it actually being a parable spoken years before.

From the very beginning you have the seed of discord in conflicting theological views of Protestantism, how can all these different movements from Lutheran to Reformed and also the current number of Protestant denominations at 35,000+ and counting, have any element of truth to them?
