If you want to read 3 good posts, read these:
1. Explicit New Testament example of St. Paul praying for the dead:
2. St. Paul teaching the Eucharistic Sacrifice/Sacrifice of the Mass:
3. The relationship between Lutheranism and St. Augustine
I like the one quote from Melancthon:
"Augustine is not in agreement with the doctrine of Paul, though he comes nearer to it than do the Schoolmen. I quote Augustine as in entire agreement, although he does not sufficiently explain the righteousness of faith; this I do because of public opinion concerning him."
so much for the claims of being an "Augustinian" tradition...
