Continuationism is a Christian theological belief that the gifts of the Holy Spirit have continued to the present age, specifically those sometimes called "sign gifts", such as tongues and prophecy. Continuationism is the opposite of cessationism.
Continuationists believe that the miraculous gifts of the Holy Spirit are still distributed today, are still in use, and are still needed in the church. The same Holy Spirit that the Apostle Paul wrote of, claiming that it gave him supernatural abilities, was also written about in the Old Testament, which claims that it also endowed such abilities upon those whom God chose to accomplish his works, as in the New Testament.
