Not much is written about Andrew in Scripture, except that he was made an apostle, and he was always mentioned in order after his brother, Simon Peter.
Andrew is mostly remembered for announcing to Peter that he and another disciple of John the Baptist had found the Messiah.13 And when it was day, He called unto Him His disciples: and of them He chose twelve, whom also He named apostles;
14 Simon, (whom he also named Peter,) and Andrew his brother, James and John, Philip and Bartholomew...
They talked with Him, and spent many hours with Him. Then Andrew brought his brother to see Jesus.
We find this narrative in the gospel of John the Evangelist.
35 Again the next day after John stood, and two of his disciples;
36 And looking upon Jesus as he walked, he saith, Behold the Lamb of God!
37 And the two disciples heard him speak, and they followed Jesus.
38 Then Jesus turned, and saw them following, and saith unto them, What seek ye? They said unto him, Rabbi, (which is to say, being interpreted, Master,) where dwellest thou?
39 He saith unto them, Come and see. They came and saw where he dwelt, and abode with him that day: for it was about the tenth hour.
40 One of the two which heard John speak, and followed him, was Andrew, Simon Peter's brother.
41 He first findeth his own brother Simon, and saith unto him, We have found the Messias, which is, being interpreted, the Christ.
42 And he brought him to Jesus. And when Jesus beheld him, he said, Thou art Simon the son of Jona: thou shalt be called Cephas, which is by interpretation, A stone.
Christ turned and spoke to Andrew and the other disciple of John.
They addressed Him, "Rabbi", or Master, recognizing Him to be One of authority and Deity.
After having spent the day with Christ, Andrew "first findeth his own brother" to announce that they had found the Messiah. Then Andrew brought his brother to see Christ.
When Jesus looked at Peter, He said, "You are Simon, the son of Jona, and you will be called Cephas." In Greek and Aramaic, Cephas is translated Peter, and is also the word for stone.
Historically, we know that Andrew lived in the fishing village of Bethsaida along the sea of Galilee with his brother, Peter, and his father, Jona.
Andrew suffered a similar end to his life as his brother: death by crucifixion.
He was tied to a cross with ropes.
"The incident depicted, the martyrdom of Saint Andrew, was supposed to have taken place in Patras, Greece. The saint, bound to the cross with ropes, was said to have survived two days, preaching to the crowd and eventually converting them so that they demanded his release. When the Roman Proconsul Aegeas - depicted lower right - ordered him taken down, his men were struck by a miraculous paralysis, in answer to the saint's prayer that he be allowed to undergo martyrdom."
