Thats because I think Calvin and Luther only disagreed on Pre-destination. (universiatly of grace) and real phyical presence.
Although honestly the real presence thing gets me fired up. I should probably avoid that debate because I just do not see how anyone could belive that that Christ only ment "In spirit"
And thats something that almost every protestant church other then Lutherans teach.
(Which is the main reason why I really don't think I could leave the Lutheran church. Taking communion in a church that doesn't belive that would be like spitting on Christ to me.) but thats just me, I'm extremly opinionated about that.
BTW, Luther, I disagree with you concerning the communion. I am a Baptist, ergo I believe in the bread and wine being nothing more than a mere representation (that is, a reminder) of the death and resurrection of Jesus Christ. But you are correct, another debate for another day.
No one can argue with scripture and we scripturally proved children are sinners from brith and that accepting Christ is not something done out of a decision of our own.
