calvin's greatest help to the english-speaking people was by giving marian exiles in geneva protection. he did this starting in 1555. with the city's protection, they could make their own reformed church under john knox and william whittingham. they later carried many of calvin's ideas back to england and scotland. however, calvin was most interested in trying to change his homeland, france. he helped the building of churches by giving out literature and offering ministers. between 1555 and 1562, over one hundred ministers were sent to france.
