📖 Biblical Definition
Pouring (affusion) is the mode of baptism in which water is poured over the candidate’s head — distinct from immersion (going completely under) and aspersion (sprinkling). Its biblical warrant is the outpouring imagery of the Spirit’s coming, which baptism signifies: "And it shall come to pass afterward, that I will pour out my spirit upon all flesh" (Joel 2:28); Peter at Pentecost: "this Jesus hath God raised up, whereof we all are witnesses... he hath shed forth [poured out] this, which ye now see and hear" (Acts 2:32-33). The Reformed and Presbyterian traditions have historically practiced pouring (or sprinkling) on this basis, especially for the baptism of infant covenant children. The mode varies; the meaning of union with Christ does not.
📜 Webster 1828 Definition

Affusion was widely practiced in the early church when full immersion was impractical — in households (Acts 16:33, the Philippian jailer at midnight), in deserts (the Ethiopian eunuch had to use what water was available), or for the sick.
Many Roman Catholic, Lutheran, and Anglican traditions practice pouring as the standard mode, especially for infant baptism.

⚠️ Modern Corruption
Some Christians dismiss pouring as compromise; the outpouring-of-the-Spirit typology is biblically explicit and the practice ancient.

Joel 2:28 / Acts 2:17 says God pours out the Spirit. The verb is poured. The image is poured. Pentecost was an outpouring, not an immersion. The pouring mode of baptism takes its typology seriously.
The Didache, the earliest Christian manual outside the New Testament, instructs: baptize... in living water. But if you have not living water, baptize in other water; and if you cannot do so in cold, in warm. But if you have neither, pour out water three times upon the head. Practical accommodation, biblical typology, ancient practice.
