I indeed have baptized you with water: but he shall baptize you with the Holy Spirit.
All Commentaries on Mark 1:8 Go To Mark 1
Bede
AD 735
It is evident that John not only preached, but also gave to some the baptism of repentance; but he could not give baptism for the remission of sins . Forthe remission of sins is only given to us by the baptism of Christ. It is therefore only said, “Preaching the baptism of repentance for the remission of sins;” for he “preached” a baptism which could remit sins, since he could not give it.
An example of confessing their sins and of promising to lead a new life, is held out to those who desire to be baptized, by those words which follow, “confessing their sins.”.
It says, clothed in a garment of hair, not in woollen clothes; the former is the mark of an austere garb, the latter of effeminate luxury. But the girdle of skins, with which he was girt, like Elias, is a mark of mortification. And this meat, “locusts and wild honey,” is suited to a dweller in the wilderness, so that his object in eating was not the deliciousness of meats, but the satisfying of the necessity of human flesh.
The dress and food of John may also express of what kind was his inward walk. For he used a dress more austere than was usual, because he did not encourage the life of sinners by flattery, butchid them by the vigour of his rough rebuke; he had a girdle of skin round his loins, for he was one, “who crucified his flesh with the affections and lusts.” He used to eat locusts and wild honey, because his preaching hadsome sweetness for the multitude, whilst the people debated whether he was the Christ himself or not; but this soon came to an end, when his hearers understood that he was not the Christ, but the forerunner and prophet of Christ. For in honey there is sweetness, in locusts swiftness of flight.
Thus then John proclaims the Lord not yet as God, or the Son of God, but only as a man mightier than himself. For his ignorant hearers were not yet capable of receiving the hidden things of so great a Sacrament, that the eternal Son of God, having taken upon Him the nature of man, had been lately born into the world of a virgin; but gradually by the acknowledgment of His glorified lowliness, they were to be introduced to the belief of His Divine Eternity. To these words, however, he subjoins, as if covertly declaring that he was the true God, “I baptize you with water, but he shall baptize you with the Holy Spirit.” For who can doubt that none other but God can give the grace of the Holy Spirit.
Now we are baptized by the Lord in the Holy Spirit, not only when in the day of our baptism, we are washed in the fount of life, to the remission of our sins, but also daily by the grace of the same Spirit we are inflamed, to do those things which please God.
