But, some people argue, what about the fact that the only sanctioned relationship in the Bible is between a man and a woman? Well, in fact, that's not quite the case. The story of the faithful centurion, told in Matthew 8:5-13 and Luke 7:1-10, is about a Roman centurion who comes to Jesus and begs that Jesus heal his pais, a word sometimes translated as "servant." Jesus agrees and says he will come to the centurion's home, but the centurion says that he does not deserve to have Jesus under his roof, and he has faith that if Jesus even utters a word of healing, the healing will be accomplished. Jesus praises the faith of the centurion, and the pais is healed. This tale illustrates the power and importance of faith, and how anyone can possess it. The centurion is not a Jew, yet he has faith in Jesus and is rewarded.
Also, Robert Gagnon, leading expert on biblical sexuality, also has dealt with this argument extensively (“Did Jesus Approve of a Homosexual Couple in the Story of the Centurion at Capernaum”). Gagnon’s salient point are:
(1) Sex with male slaves not a universal phenomenon.
(2) Jesus would have had to have been endorsing rape in this case.
(3) Jesus’ fraternization with tax collectors and sexual sinners does not suggest support for their behavior.
(4) The Jewish elders in Luke 7 could not have supported a homosexual relationshi.
(5) Q, Matthew, and Luke did not interpret Jesus’ healing as support for same-sex intercourse.
(6) Historical Jesus study does not support a pro-homosex reading.
