For its first half-century, Pentecostal experience was largely confined to Pentecostal denominations. That changed in the 1960s. Believers in the Episcopal, Lutheran, Presbyterian, and other mainline churches — and, from 1967, in the Roman Catholic Church — began to seek and receive the gifts of the Spirit.
Crucially, most did not leave their churches. The Charismatic Renewal was a movement within existing traditions, not a new denomination: a Catholic charismatic remained Catholic, an Anglican charismatic remained Anglican. It carried Pentecostal worship and expectancy into communities that had not known them.
The Renewal reshaped worship across a wide span of Christianity — informal praise, an openness to the Spirit's gifts, a warmth of expression. Its lineage runs directly back to the Pentecostal movement, and through it to the Holiness and Methodist revivals before.
