Guido you do insult someone when you ask for commentary suggestions then accuse them of "opposing the gospel" because they are a Calvinist. I forgive you though because the description of "Calvinism" you give shows that you don't know what it is either. As you are seeing, no non-Calvinists are suggesting any commentaries. That is one of the main reasons I became a Calvinist - most haters of Calvinism have no workable theology and that is in many cases on purpose.
If I could make a suggestion that might be acceptable to you. It would be William Newell, "Romans Verse by Verse".
He did teach God's sovereignty but was against a limited atonement. The book is old enough that he knew nothing of the modern debates. It's still in print on Amazon and if you look around you can get a paperback for 5 dollars or so.
Thanks. I'll definitely read it.
If Calvinists don't teach random selection for salvation, then what do they teach about unconditional election?
