1 The First Article of our Confession our adversaries approve, in which we declare that we believe and teach that there is one divine essence, undivided, etc., and yet, that there are three distinct persons, of the same divine essence, and coeternal, Father, Son, and Holy Ghost.
1 This article we have always taught and defended, and we believe that it has, in Holy Scripture, sure and firm testimonies that cannot be overthrown. And we constantly affirm that those thinking otherwise are outside of the Church of Christ. and are idolaters, and insult God.
