I'm reading Martin Marty's biography of Martin Luther. I can't make myself like Calvin, but there's something about ol' Martin, he of all the Reformers I think really knows Catholicism. It's funny because I thought as a Catholic Luther would be less appealing, but actually his writing becomes more appealing, because all of his complaints I can now truly identify with. I've heard other Catholics ask the same questions he asked, and heard priests give me his solutions to the same problems (I guess he was more successful than Catholics would like to admit).
Lutheranism I also find appealing because of it's faithfulness to regenerative baptism and the real presence of Christ in the Eucharist (and I think Consubstantiation/Sacramental Union is more defensible than Transubstantiation). The main appeal though - the reason a friend of mine said he is Lutheran - is the appeal of the Theology of the Cross, rather than the Theology of Glory.
Of course the other reason I like Lutheranism is because I haven't actually been to a Lutheran Church service, so I can't come up with any personal complaints. It is still an ideal, not a reality.
I'm not saying I'm converting or anything, I'm just saying I really like alot of what Luther had to say, and can empathize with his story. (I spent literally 8 hours today thinking about Justification, all day at work, trying to find SOME way to make Catholicism sound gracious...no luck so far)
