For much of his life, John Calvin had two close friends -- Farel and Viret. Farel was very hot-headed and out-spoken, while Viret was of very mild temperament, an instinctive peace-keeper. Farel often came to Geneva and stayed at Calvin's home, where, sometimes with Viret, the friends would have long talks about theology and current events over a glass. Calvin delighted in the company of his zealous friend. Nevertheless, as time went on he came to see that Farel's inflexible nature made him a doughty defender but a limited propagator of the gospel. He often sent his own discourses and letters to Viret, whose job was to moderate his language. Calvin himself had been more hot-headed as a young man, and he worked to curb his own tongue.
