'...the language of liberalism fails to engage on common terms with the communion of saints and the Lordship of Christ. Arguments about sexuality that dispense with the theological logic and that are premised on human autonomy and experience are incongrous in debates within the churches, even when glossed with appeals to justice or love, for such liberal arguments suggest that we can know ourselves sufficiently apart from revelation and doctrine, as if there were parts of life removed from God's grace, address, vocation, command, judgment, or teleology.'
