One mightier than I is coming, whose sandal strap I am not worthy to loose. He will baptize you with the Holy Spirit and with fire. Luke 3:16.
True and stable faith is baptized with water, unto salvation. Pretended and weak faith is baptized with fire, unto judgment. Tertullian (c. 198, W), 3.674.
John said that we must be baptized in the Holy Spirit and in fire. Because he said “and fire,” . . . very crafty men seek a way to thereby corrupt and violate—and even neutralize—the baptism of holiness. They derive the origin of their notion from Simon Magus, practicing it with manifold perversity through various errors. . . . However, those who are not ignorant of the nature of the Holy Spirit, understand that what is said about fire is said about the Spirit Himself. For in the Acts of the Apostles, . . . they were baptized with the Holy Spirit and with fire. That is, they were baptized with the Spirit. . . . This was similar to the fire that burned in the bush, but did not consume the bush. Treatise on Re-Baptism (c. 257), 5.676, 677.
