Whose fan is in his hand, and he will thoroughly purge his floor, and gather his wheat into the barn; but he will burn up the chaff with unquenchable fire.
All Commentaries on Matthew 3:12 Go To Matthew 3
Jerome
AD 420
In the other Gospels it is, “whose shoe latchet I am not worthy to loose.” Here his humility, there his ministry is intended; Christ is the Bridegroom, and John is not worthy to loose the Bridegroom’s shoe, that his house be not called according to the Law of Moses and the example of Ruth, “The house of him thathath his shoe loosed.” John who is carnal cannot give spiritual baptism; he baptizes with water, which is matter; so that he baptizes matter with matter. Christ is Spirit, because He is God; the Holy Spirit is Spirit, the soul is spirit; so that Spirit with Spirit baptizes our spirit. The baptism of the Spirit profits as the Spirit enters and embraces the mind, and surrounds itas it were with an impregnable wall, not suffering fleshly lusts to prevail against it. It does not indeed prevail that the flesh should not lust, but holds the will that it should not consent with it.And as Christ is Judge, He baptizes in fire, i.e. temptation; mere man cannot baptize in fire. He alone is free to tempt, who is strong to reward. This baptism of tribulation burns up the flesh that it does not generate lust, for the flesh does not fear spiritual punishment, but only such as is carnal. The Lord therefore sends carnal tribulation on his servants, that the flesh fearing its own pains, may not lust after evil. See then how the Spirit drives away lust, and suffers it not to prevail, and the fire burns up its very roots.
Either the Holy Spirit Himself is a fire, as we learn from the Acts, when there sat as it were fire on the tongues of the believers; and thus the word of the Lord was fulfilled who said, “I am come to send fire on the earth, I will that it burn.”
