The Spirit of Christ does not advocate for a position that is 180 degrees opposed to Christ’s own positions, including Jesus’ rigorous application of the moral logic of God’s creation of a sexual binary for limiting the number of partners in a sexual relation to two (Mark 10:2-12 par. Matt 19:3-9). In those instances, it is more accurate to talk about conformity to “the spirit of our age” rather than to Christ’s Spirit.
