When Sabellianism, thus encouraged, came openly forward, and defended its system and won adherents, then Church Orthodoxy would hasten to set up barriers on that side, and would fall back upon Tritheistic ground, making the Threefold Personality a profound and real distinction, penetrating the very nature of Deity, and changing the Unity of Being into a mere Unity of Will or agreement.

But it would seem that these efforts had but a qualified success, for on February 12th, 1720, the Lords condemned a work which, "in a daring, impious manner, ridiculed the doctrine of the Trinity and all revealed religion," and was called, A Sober Reply to Mr. Higgs' Merry Arguments from the Light of Nature for the Tritheistic Doctrine of the Trinity, with a Postscript relating to the Rev.
