How far do we take “everything is permissible”? If Christianity is license, the terms of it have nothing to do with morality and as such, all things are gauged by practicality, by fruit. One would then have to wonder about Christians and their moral objections to the role of women in the Church, Christian homosexuality, marriage in the priesthood and so on.
Christians have yet to adopt an appropriate language that takes Paul’s philosophy to heart; one that speaks to what matters about sin, what doesn’t, and is subsequently devoid of ideas of judgment.
Just a thought.
