Macarius of Jerusalem
4th century Bishop of Jerusalem
Feast: 10 March (not on the universal Roman calendar; kept in the Roman Martyrology or local calendars)
Who they were
Macarius was Bishop of Jerusalem from about 312 until shortly before 335. He was one of the bishops whom St. Alexander of Alexandria warned against Arius, and Arius's abusive words about him show how firmly he opposed the new heresy. He took part in the Council of Nicaea, and his name heads those of the bishops of Palestine who signed it.
After the council, excavations were begun at Jerusalem, apparently under his direction: the mound and pagan temple built over the tomb of Christ in Hadrian's time were cleared away and the Holy Sepulchre was found. The Emperor Constantine then wrote to Macarius ordering a church to be built on the site.
The miracles
There was never a formal cause: he has been honoured as a saint since before the Church's formal processes began.
Why that counted as sanctity
The bishop of Jerusalem who opposed Arius and oversaw the uncovering of the Holy Sepulchre.
