The Agape Vespers, which close the first day of the Feast of Feasts, put forward the Gospel reading of John 20: 19 – 25. In this passage, Jesus appears to the disciples in his glorified body. He commissions them as his apostles, exhales the Holy Spirit to them, and then is gone. Thomas was absent. Upon his return the others declare to him their experience, and proclaim the resurrection of Jesus. But, Thomas doubts: “Unless I cast my finger into the nail wholes in his hands, and cast my hand into his side [wound from the roman’s spear], I shall not believe” (John 20: 25). His doubts will last only another week:
And after eight days his disciples were inside and Thomas was with them. While the doors were locked, Jesus came and stood in their midst and said, “Peace to you.” Then he says to Thomas, “Place your finger here and behold my hands and cast you hand into my side, and do not be faithless, but faithful!” Thomas answered and said to him, “My Lord and my God!” (John 20: 26 – 28).
