(The above does not represent my opinion or position, but was accessible on the internet.)
The Bible consistently defines marriage as the union of one man and one woman. In Genesis 2:24, God joins Adam and Eve, saying they will become “one flesh.” Jesus reaffirms this in Matthew 19:4–6, pointing to creation where God “made them male and female.” This male-female pairing reflects God’s design for marriage and is foundational for procreation and the family unit. No biblical passage redefines marriage outside this male-female structure.
Therefore, I cannot see how any church can, in all good conscience, perform a same-sex wedding!
