After working with both the English-only, the Greek-only, and the Greek-English editions of Kurt Aland’s Synopsis of the Four Gospels, I have decided to purchase the Greek-English edition. I have found it cumbersome to navigate between my Accordance software and my English Synopsis. I have found my Greek Synopsis to have too much German that I cannot translate on the fly. So contrary to Gordon Fee, whose exegetical insights and resource recommendations I highly respect, the Greek-English edition is the winner here.
I have also purchased the new Thomas Aquinas Commentary on the Gospel of John, Books 1-5. Part of the influence for this is the involvement of Matthew Levering, whose knowledge on Aquinas is top notch.
