Makes one wonder what John Quincy Adams saw in Unitarianism?
It begab as a hyper rational deism that denied the Trinity and the Incarnation and other more commonly held Christian beliefs. There’s a stretch of road in Mass. where there’s an an ancient colonial church with an early 19th century church right next door both with the same name but the newer church has “Trinitarian” in parens at the bottom. Evidence of a doctrinal war.
