I caught a portion of the first part of a commentary on the Gospel of John, on 9/22/2019. There are supposed to be 3 or 4 more installments in the upcoming weeks. If your station does not carry the program, you can come back to the radio archive for the subsequent parts of the commentary.
I don’t know the priest who was giving the talk, but he made an enlightening remark about the Baptism of Jesus. He referred to the account in Luke about how John the Baptist says he was unworthy to untie the strap of Jesus’s sandal. He links this with the account of the sandal in Ruth 4:7 to highlight how the gospels account Jesus as the eternal Bridegroom of the Church.
