During the 16th century, from 1536 onwards, the National Protestant Church of Geneva was in constant turmoil through the insistence on, and the opposition to, the doctrines laid down by Calvin in his Confession of Faith and System of Ecclesiastical Ordinances. The 17th century is marked by the conflicts of Calvinism and Arminianism. After numerous variations, the oath of consecration was, in June 1725, changed hack to the form provided by the Ecclesiastical Ordinance of 1576: "You swear to hold the doctrine of the holy prophets and apostles, as it is contained in the books of the Old and New Testaments, of which doctrine our Catechism is a summary ". This oath remained in force for nearly a century, till 1806. "It was asserted in the discussion (in the Assembly) that no one should be forced to follow entirely Calvin's Catechism. It is further expected that the candidates for the ministry should be requested not to discuss in the pulpit any striking or useless matter which might tend to disturb the peace. At this time, the Confession of Faith of the 17th century was abolished to return to that of the 16th century, interpreting the latter with much freedom. The Lower Council ratified this decision, but ordered the Assembly to keep the most absolute silence upon this subject, especially in the presence of strangers." In 1788, the Assembly adopted a new Catechism, containing numerous points of divergence from the orthodox Catechism of Calvin, which it superseded with the sanction of the Lower Council. In 1806, the new formula of consecration threw out the Catechism; it ran thus--"You promise to teach divine truth as it is contained in the books of the Old and New Testaments, of which we have an abridgment in the Apostles' Creed". In 1810, after long deliberation, there was published a revision in the latitudinarian and utilitarian sense of the Larger Catechism. In the same year, the Apostles' Creed was thrown out of the pledge of the ministers, which now read thus: "You promise ... to preach, in its purity, the gospel of our Lord Jesus Christ, to recognise as the only infallible rule of faith and conduct the word of God, as it is contained in the sacred books of the Old and New Testaments". Presently, however, in 1813, a religious revival led to dangerous discussions, and the ministers were bound "to abstain from all sectarian spirit, to avoid all that would create any schism and break the union of the Church"--an addition suppressed towards 1850; and in 1817, they were required to pledge themselves to abstain from discussing four points in particular--the manner of the union of the divine and human nature in the person of Jesus Christ; original sin; the manner in which grace operates, or saving grace; and predestination; and, if led to utter their thoughts on any one of these subjects, they were "to do so without too much positiveness, to avoid expressions foreign to the Holy Scriptures, and to use, as much as possible, the terms which they
