few volumes were written in the now defunct wycliffe exegetical commentary, and it is a darn shame. we're all familiar with douglas moo (conservative evangelical from trinity evangelical seminary) and this commentary is one of the best. in general the most respected volume on Romans is the one by cranfield (international critical commentary). another is that by fitzmyer. these two are written from a more academic position (if you didn't know fitzmyer was a catholic priest you might sometimes doubt his belief altogether). for those of us who are conservative but yet academically bent, this is the best, or rather was the best, longer than either cranfield or fitzmyer, and with more language analysis. i don't think moo ever finished the second volume; instead he redid both in his one volume commentary in the NICNT series. if you want to really study Romans ( and are more concerned with the text itself and less about interacting with liberal german scholars ), you would do well to find an old copy. by the way, no offense meant to fitzmyer!
