Bede, on 1Pet 5:1

“The ancients therefore that are among you, I beseech, who am myself also an ancient, and a witness of the sufferings of Christ: as also a partaker of that glory which is to be revealed in time to come:”

“Who is also a partaker of the glory that is to be revealed in the future. Clearly, this happened when on the holy mountain he beheld the heavenly glory of His face with James and John, or when he saw the power of His resurrection and ascension with the other disciples who were present.”
