believers. In medieval Catholicism, believers remained anxious about their spiritual destinies and were required to perform more and more good works to guarantee their salvation. Calvin taught that once a believer understands he is chosen by Christ to eternal life, he will never have to suffer doubt again about salvation: “He will obtain an unwavering hope of final perseverance (as it is called), if he reckons himself a member of him who is beyond hazard of falling away.”
