Aka Saint James, the Brother of Jesus, the Brother of our Lord, Yaacov HaTzadik, the dude who wrote the book of James.
Accounts of this guy from the Church Fathers tend to amaze me. My personal favorite comes from Hegesippus (from a lost commentary that happens to have been quoted by St. Jerome):
After the apostles, James the brother of the Lord surnamed the Just was made head of the Church at Jerusalem. Many indeed are called James. This one was holy from his mother’s womb. He drank neither wine nor strong drink, ate no flesh, never shaved or anointed himself with ointment or bathed. He alone had the privilege of entering the Holy of Holies, since indeed he did not use woolen vestments but linen and went alone into the temple and prayed in behalf of the people, insomuch that his knees were reputed to have acquired the hardness of camels’ knees.
Now I’m not sure about the whole not bathing thing, and anyone that knows much about first century Judaism can tell you that the bit about the Holy of Holies is wrong, as James was never high priest. However:
1) James was obviously a Nazarite, which meant he had made a vow to God.
2) I’m not so sure about the accuracy of the “camel knees,” but I do find it interesting to think that someone would spend so much time on their knees in prayer that they would develop callouses.
One thing is for certain, James was a Godly man and an example more of us could stand to look to.
