Yes, I would like to talk to a Greek scholar as well. A conviction of what the Greek says there certainly be extremely helpful. The preponderance of English versions as well as a cursory glance at the Greek seem to certainly allow for God as the foundation.
Certainly the scripture is self-interpreting on the issue of the sinfulness of mankind which was my original point. The idea of the sinfulness of all (excepting Christ) is consistent throughout the Bible.
No, of course, I wouldn't agree with all those Protestant commentators if they disagreed with what the Church teaches. I just cited them to show that the idea of reading the appositive as referring to the word "Church."is a lot more widespread than just within Catholicism.
Googling around like that also illustrates another important point: that there is commonly a lot of disagreement amongst guys like this about doctrine, which is why I usually go first to a reliable, coherent, and internally consistent source of interpretation, i.e. the Catechism.
I'm out to an all-day Shape-Note Singing!~
