Since the discussion keeps circling around water & purification, it's time to step back & let Scripture define its own categories. Once the Jewish purification framework is laid out, the New Covenant shift from water washing to Spirit purification becomes impossible to miss
Mosaic Law required numerous ceremonial water purification rituals (ablutions): washing hands, feet, bodies, garments & sacred vessels. Jewish law recognized three primary forms: hand washing, hand & foot washing & full‑body immersion in a mikveh (JewishEncyclopedia.com). On the Day of Atonement, the High Priest washed his hands & feet 10 times & immersed his body 5 times. Other priestly duties required additional purifications (Ex 30:19–21; Lev 6:27; 14:8–9; 15:16; 16:4, 24; 22:6)
Every Mosaic observant Israelite understood these washings. A full mikveh immersion expressed:
I acknowledge I'm unclean, I'm turning from that state, I'm returning to covenant faithfulness, I'm restoring my ritual status before God and the community
(Sources: Jewish Virtual Library; Sefaria; Rabbi Samson R. Hirsch)
The pattern was always the same:
Unclean > immerse > clean - Impure > immerse > pure - Out of fellowship > immerse > restored. But these immersions never removed sin. They restored ritual purity, not spiritual regeneration
Jacob purified his household before meeting the Lord at Bethel (Gen 35).
Israel purified themselves before meeting the Lord at Sinai (Ex 19).
John the Baptist prepared Israel to meet the Lord (Mal 3:1; Matt 3:3; Mark 1:2–3; Luke 3:4).
John's baptism of repentance was a traditional Jewish purification immersion. They confessed their sins, acknowledging they were out of fellowship, outside the covenantal markers & immersion restored their ritual standing before God & the community.
John's baptism prepared Israel for the Messiah, through whom remission of sins would come (Acts 19:4). John operated entirely under Mosaic Law & did not baptize Gentiles (Matt 3:1). In Hebrew/Aramaic, repent (שׁוּב, shuv) means “return to the Lord your God.” John's baptism did not save or remit sin.
Acts is a transitional book, mapping the shift from the Old Covenant's physical circumcision (Gen 17:1–14; Acts 7:8) to the New Covenant's spiritual circumcision of Christ (Col 2:11). Pentecost occurred on the Temple Mt & the categories in Acts 2 are entirely Jewish. Archaeologists have documented more than a hundred mikva’ot around the Temple Mount, especially at the Southern Steps where Acts 2 unfolded.
John 3:25 records a dispute about purification, not forgiveness. This is how Jews interpreted immersion. John & Jesus' disciples practiced a baptism of repentance. A ceremonial purification preparing Israel to return to & meet the Lord
Acts 19:4 confirms this: John's baptism was preparatory, pointing people to Christ. None of Israel’s ceremonial washings, including water baptism, remitted sin or granted eternal life. They restored ritual purity, not spiritual regeneration.
Under the New Covenant, Scripture consistently attributes true cleansing, washing, sanctifying & purifying to the Holy Spirit, not to water.
Titus 3:5, the washing of regeneration and renewal of the Holy Spirit - 2 Thes 2:13, sanctification by the Spirit - Rom 15:16, sanctified by the Holy Spirit - 1 Cor 6:11, washed-sanctified-by the Spirit of our God - 1 Pet 1:2, in the sanctification of the Spirit - Acts 15:9, purifying their hearts by faith
Across multiple authors, Paul, Peter & Luke the pattern is identical: The Spirit is the purifier. Water is the symbol
And the major lexicons agree: Sanctification = purification & purification is the Spirit's work.
BDAG: to purify, cleanse from moral defilement - TDNT: cleansing, removal of impurity, purification - Louw–Nida: to purify, to cleanse, to make holy
So when the Spirit fell in Acts 10, the purifier Holy Spirit/Himself acted. Water follows, it never causes.
The baptism of the Holy Spirit remits sin, purifies the heart, grants eternal life & brings a person into the New Covenant. This baptism is performed by Jesus alone (Matt 3:11; Mark 1:8; Luke 3:16; John 1:33). No human hands, no ritual water. NEW COVENANT FULFILLMENT: Holy Spirit Baptism as the True Purifier!
Through the Holy Spirit baptism, believers are placed into the body of Christ- by one Spirit (1 Cor 12:13). This is the New Covenant counterpart to the Old Covenant's physical initiation rite. Paul calls it - the circumcision made without hands & the spiritual circumcision of Christ (Col 2:11). It is the inward purification of the heart (Rom 2:29), the very thing Israel's external washings symbolized but could never accomplish.
This Spirit‑given baptism is also God’s eternal salvation seal:
The Spirit abides FOREVER (Jn 14:16) - Believers are SEALED with the Holy Spirit of promise (Eph 1:13–14) - SEALED unto the day of redemption (Eph 4:30) - the Holy Spirit is God's earnest/DOWN PAYMENT guaranteeing our inheritance (2 Cor 1:22; 5:5) - the Holy Spirit poured into our hearts is the assurance of God's love (Rom 5:5) the Holy Spirit guards the salvation entrusted to us (2 Tim 1:14)
When Jesus immerses & SEALS a believer with/by/in the Holy Spirit, He accomplishes what every mikveh, every ablution, every priestly washing, every purification rite & John's baptism of repentance symbolize
The baptism of the Holy Spirit is the New Covenant fulfillment of all Israel's Old Covenant purification rituals. Water rituals pointed to it. The Spirit performs it. Jesus alone administers it.
From Moses to John to Jesus to Peter to Paul, the pattern never changes: water symbolized purification, but the Holy Spirit performs it. When Jesus baptizes with the Holy Spirit, every Old Covenant washing finds its fulfillment. Water follows & never causes eternal life or sin remittance.
