Saint Nicanor, Apostle of the Seventy was among the first deacons in the Church of Christ. In the Acts of the Holy Apostles (6: 1-6) it is said that the twelve Apostles chose seven men: Stephen, Philip, Prochorus, Nicanor, Timon, Parmenas and Nicholas, full of the Holy Spirit and wisdom, and established them to serve as deacons.
The Holy Church celebrates their memory together on July 28, although they died at various times and in various places.
St Nicanor suffered on that day when the holy Protomartyr Stephen and many other Christians were killed by stoning. SOURCE:
