First of all, as a new believer, I want to tell you how helpful and wonderful Dr. Fruchtenbaum’s book “The Footsteps of the Messiah” has been to me. I have learned very much. I have a question about the Apostle Peter. Was he really hung upside down on the cross or was he hung on the cross as was Jesus only with his head down?
Yes, Peter was crucified in an upside down position, per his own request as explained in 1 Clement 5:1-6:1 and alluded to in John 21:18-19.
