"The earliest known use of the word deist was by Pierre Viret, a disciple of John Calvin, in his Instruction chrétienne (Geneva, 1564), Vol. II, "Epistre" (signed, Lyons, December 12, 1563). Viret regarded it as an entirely new word that (he claimed) the deists wished to oppose to atheist: According to him, the deist professes belief in God as the creator of heaven and earth but rejects Jesus Christ and his doctrines."
