Final answer:
Reformation leaders like Martin Luther and John Calvin asserted that the gifts of the Holy Spirit had ceased with the early apostolic church, focusing instead on salvation and scriptural authority.
Step-by-step explanation:
The Reformation leaders responded to the idea of a restoration of the Spirit's power by c) asserting that the gifts of the Holy Spirit had ceased with the passing of the apostolic church. This position, known as cessationism, holds that the miraculous gifts of the Holy Spirit, such as speaking in tongues and healing, were only meant for the early church and are no longer necessary or available. The leaders of the Reformation, including prominent figures such as Martin Luther and John Calvin, were focused on doctrinal issues around salvation, and the authority of scripture, and distanced themselves from the mystical and supernatural aspects attributed to the Holy Spirit during the apostolic age.
