Caroli brought a counter-charge against the Geneva divines of Sabellianism and Arianism, because they would not enforce the Athanasian creed, and had not used the words "Trinity" and "Person" in the confession they had drawn up. It was a struggle between the thoroughgoing humanistic reformer who drew his creed solely from the "word of God" and the merely semi-Protestant reformer who looked on the old creed as a priceless heritage.
The new type passed on into the West through Augustine, and the so-called Athanasian creed, which states an s Augustinian version of Greek dogma.
It enjoins public reading of certain lessons from the Apocrypha and uses in worship even the " Athanasian " as well as the two more ancient creeds.
About the same time (1747) he finally left the Anglican communion for the Baptist, leaving the church literally as well as figuratively by quitting it as the clergyman began to read the Athanasian creed.
But, though in 1680 he published his Unreasonableness of Separation, his willingness to serve on the ecclesiastical commission of 1689, and the interpretation he then proposed of the damnatory clauses of the Athanasian creed, are proof that to the end he leaned towards toleration.
