Episode 1057 The Reasons for the Five Holy Wounds

The five wounds comprised 1) nail holes, one through each hand or wrist, 2) nail holes, one through each foot, 3) a wound to the torso from the piercing of the spear, 4) wounds around the head from the crown of thorns, and 5) lash marks from the flagellation.

Two of the wounds were through either his hands or his wrists, where nails were inserted to fix Jesus to the cross-beam of the cross on which he was crucified.
Two were through the feet where the nail(s) passed through both to the vertical beam.
The final wound was in the side of Jesus' chest, where, according to the New Testament, his body was pierced by the Lance of Longinus in order to be sure that he was dead. The Gospel of John states that blood and water poured out of this wound (John 19:34). Although the Gospels do not specify on which side he was wounded, it was conventionally shown in art as being on Jesus's proper right side, though some depictions, notably a number by Rubens, show it on the proper left.
The examination of the wounds by "Doubting Thomas" the Apostle, reported only in the Gospel of John at John 20:24–29, was the focus of much commentary and often depicted in art, where the subject has the formal name of the Incredulity of Thomas.
