The Charismatic movement began in the early 1960s in mainline denominations such as the Episcopal, Roman Catholic, Presbyterian, etc. It has become one of the fastest growing movements in the church today. Fundamentally, the movement shares many beliefs and practices with Pentecostal churches with some differences. Generally speaking, Charismatics believe the supernatural gifts of the Holy Spirit are available to Christians today through the infilling or "Baptism of the Holy Spirit" as described in the New Testament Scriptures such as Acts chapter 2. Hence the term "Spirit-filled."
