The collect for today, the Feast of Saint Andrew, Apostle and Martyr, from The Book of Common Prayer (Canadian, 1962):
ALMIGHTY God, who didst give such grace unto thy holy Apostle Saint Andrew, that he readily obeyed the calling of thy Son Jesus Christ, and followed him without delay: Grant unto us all, that we, being called by thy holy word, may forthwith give up ourselves obediently to fulfil thy holy commandments; through the same Jesus Christ our Lord. Amen.
A native of Bethsaida on the Sea of Galilee, Andrew was a fisherman, the son of the fisherman John, and the brother of the fisherman Simon Peter. He was at first, along with John the Evangelist, a disciple of John the Baptist. John the Baptist’s testimony that Jesus was the Christ led the two to follow Jesus. Andrew then took his brother Simon Peter to meet Jesus. In Eastern Orthodox tradition, St Andrew is called the Protokletos (the First Called) because he is named as the first disciple summoned by Jesus into his service.
At first Andrew and Simon Peter continued to carry on their fishing trade, but the Lord later called them to stay with him all the time. He promised to make them fishers of men and, this time, they left their nets for good.
The only other specific reference to Andrew in the New Testament is at St Mark 13:3, where he is one of those asking the questions that lead our Lord into his great eschatological discourse.
