A consideration of religious history

I have been giving thought lately to the reasons for why the different churches worship and believe they way they do.  As I have argued in other contexts and discussions, it all has to do with foundations. 
Going all the way back to approximately the fourth century, as the Roman patriarch began to take Jesus' words of "on this rock I will build my church" as referring to Peter alone, instead of all the apostles, the church in the west began to deviate.  From this faulty position, the Roman Catholic church began to embrace errors and finally in the 11th century, broke away from the four other patriarchates.
Five centuries later, Martin Luther, seeing some of the errors of Roman Catholicism, sought after reform within the church.  They kicked him out.  From this position and from the belief that people in general needed to know and understand scripture, he began emphasizing sermons.
Luther still held onto the importance of the sacraments and we this see both of these emphases in Lutheran churches today.
Calvin took the thought of knowledge and understanding to the next level (he being a lawyer) and the Reformation church service began to be centered around knowledge.
The problem here is the focus on what one considers most important.  While it is true that people should know the Bible and understand their faith, it is not true that the worship service is to be built around that.
Again, these leaders deviated from what the church had always practiced, they re-defined for themselves the form of worship and fell into error.  From the beginning, the Divine Liturgy has been about relationship and communion with God, not about head knowledge.  Imagine going to bed with your wife and proceeding to spend the next hour reading about what your wife does each day in her interactions with your children.  Studying those things is perfectly fine, but not at that time.  That is the time for marital communion.
The only way we are going to grow in our relationship with God, grow in holiness and become sanctified is by right worship, repentance and partaking of the sacraments.  Other things, while important, are secondary.
