Its chief pastor had persuaded him to stay as a colleague, and the council appointed him professor and preacher. He was young, exactly twenty-seven years of age, full of high ideals, but inexperienced, unacquainted with men, without any knowledge of Geneva and the state of things there. He could therefore make no terms, could only stay to do his duty. What that duty was soon became apparent. Geneva had not become any more moral in character because it had changed its mind in religion. It had two months before Calvin's arrival sworn to live according to the holy evangelical law and Word of God; but it did not seem to understand its own oath. And the man whom his intellectual sincerity and moral integrity had driven out of Catholicism could not hold office in any church which made light of conviction and conduct; and so he at once set himself to organize a church that should be efficaciously moral. He built on the ancient Genevan idea, that the city is a church; only he wished to make the church to be primary and real. The theocracy, which had been construed as the reign of the clergy, he would interpret as ideal and realize as a reign of God. The citizens, who had assumed control of their own spiritual destinies and ecclesiastical affairs, he wanted to instruct in their responsibilities and discipline into obedience. And he would do it in the way of a jurist who believes in the harmony of law and custom; he would by positive enactments train the city, which conceived itself to be a church, to be and behave as if it were indeed a church, living according to the gospel which it had sworn to obey. Thus a confession of faith was drawn up which the people were to adopt as their own, and so attain clarity and concordance of mind concerning God and his Word; and a catechism was composed which was to be made the basis of religious instruction in both the school and the family, for the citizen as well as the child. Worship was to be carefully regulated, psalm-books prepared, psalm-singing cultivated; the preacher was to interpret the Word, and the pastor to supervise the flock. The Lord's Supper was to be celebrated monthly, but only those who were morally fit or worthy were to be allowed to communicate. The church, in order that it might fulfil its functions and guard the holy table, must have the right of excommunication. It was not enough that a man should be a citizen or a councillor to be admitted to the Lord's Supper; his mind must be Christian and his conduct Christlike. Without faith the rite was profaned, the presence of Christ was not realized. Moreover, since matrimonial cases were many and infelicity sprang both from differences of faith and impurity of conduct, a board, composed partly of magistrates and partly of ministers, was to be appointed to deal with them; and it was to have the power to exclude from the church those who either did not believe its doctrines or did not obey its commandments.
