Can gays be christian

If by “gay” we mean someone whose dominant sexual attraction is to people of the same gender, then someone can be a “gay Christian.” For more information, see Is God Anti-Gay? by Sam Allberry, and the site for testimonies of Christians living with same-sex attraction.
If the phrase “gay Christian” refers to a person who actively, perpetually, and unrepentantly lives a homosexual lifestyle – no, it is not possible for such a person to truly be a Christian.
