A rewritten version of Servetus’ manuscript was secretly printed in 1,000 copies at Vienne in 1553. In discussing the relationship between the Spirit and regeneration in that book, Servetus almost incidentally made known his discovery of the pulmonary circulation of blood. In the book, Servetus argued that both God the Father and Christ his Son had been dishonoured by the Constantinian promulgation of the Nicene Creed, thus obscuring the redemptive role of Christ and bringing about the fall of the church; Servetus felt he could restore the church by separating it from the state and by using only those theological formulations that could be proved from Scripture and the pre-Constantinian fathers.
