In this visit Farel recognized the hand of God. Though Geneva had accepted the reformed faith, yet a great work remained to be accomplished here. It is not as communities but as individuals that men are converted to God; the work of regeneration must be wrought in the heart and conscience by the power of the Holy Spirit, not by the decrees of councils. While the people of Geneva had cast off the authority of Rome, they were not so ready to renounce the vices that had flourished under her rule. To establish here the pure principles of the gospel and to prepare this people to fill worthily the position to which Providence seemed calling them were not light tasks.
Farel was confident that he had found in Calvin one whom he could unite with himself in this work. In the name of God he solemnly adjured the young evangelist to remain and labor here. Calvin drew back in alarm. Timid and peace-loving, he shrank from contact with the bold, independent, and even violent spirit of the Genevese. The feebleness of his health, together with his studious habits, led him to seek retirement. Believing that by his pen he could best serve the cause of reform, he desired to find a quiet retreat for study, and there, through the press, instruct and build up the churches. But Farel's solemn admonition came to him as a call from Heaven, and he dared not refuse. It seemed to him, he said, "that the hand of God was stretched down from heaven, that it lay hold of him, and fixed him irrevocably to the place he was so impatient to leave."-- D'Aubigne, History of the Reformation in Europe in the Time of Calvin, b. 9, ch. 17.
At this time great perils surrounded the Protestant cause. The anathemas of the pope thundered against Geneva, and mighty nations threatened it with destruction. How was this little city to resist the powerful hierarchy that had so often forced kings and emperors to submission? How could it stand against the armies of the world's great conquerors?
Throughout Christendom, Protestantism was menaced by formidable foes. The first triumphs of the Reformation past, Rome summoned new forces, hoping to accomplish its destruction. At this time the order of the Jesuits was created, the most cruel, unscrupulous, and powerful of all the champions of popery. Cut off from earthly ties and human interests, dead to the claims of natural affection, reason and conscience wholly silenced, they knew no rule, no tie, but that of their order, and no duty but to extend its power. (See Appendix.) The gospel of Christ had enabled its adherents to meet danger and endure suffering, undismayed by cold, hunger, toil, and poverty, to uphold the banner of truth in face of the rack, the dungeon, and the stake. To combat these forces, Jesuitism inspired its followers with a fanaticism that enabled them to endure like dangers, and to oppose to the power of truth all the weapons of deception. There was no crime too great for them to commit, no deception too base for them to practice, no disguise too difficult for them to assume. Vowed to perpetual poverty and humility, it was their studied aim to secure wealth and power, to be devoted to the overthrow of Protestantism, and the re-establishment of the papal supremacy.
