Saint Luke was a gentile and a Greek who was born in Antioch. he lived in the 1st century and was a physician. He was the author of the Gospel (part of the holy bible) that bears his name and of its continuation, which is called 'the Acts of the Apostles'.the quote in this song is not literally taken from a sermon in the gospel of luke, but was paraphrased as a nietzschean critique on christianity by MSP, as luke 6:29 says: "If someone strikes you on one cheek, turn to him the other also. If someone takes your cloak, do not stop him from taking your tunic."
