Greek is not mentioned in Mark 15:26, but we know that the plaque over Jesus' head was written in Greek, Latin, and Hebrew because of John 19:19. It does not matter that water is not mentioned in Rom 6 or Col 2. What matters is that both of those passages state that we are saved, forgiven, cleansed of sin, and given new life in Christ through baptism.
Spirit baptism
hello
1 Corinthians 12:13 (LEB) — 13 For by one Spirit we were all baptized into one body, whether Jews or Greeks, whether slaves or free persons, and all were made to drink one Spirit.
Without the spirit you are none of his
Romans 8:9 (LEB) — 9 But you are not in the flesh but in the Spirit, if indeed the Spirit of God lives in you. But if anyone does not have the Spirit of Christ, this person does not belong to him.
And there is only one baptism in the NT Church (Eph 4:5-6), and the baptism in which we are saved is in water (1 Pet 3:21, Acts 8:36), and is performed by man (Matt 28:19, Mark 16:16).
One baptism which places us in Christ
1 Corinthians 12:13 (LEB) — 13 For by one Spirit we were all baptized into one body, whether Jews or Greeks, whether slaves or free persons, and all were made to drink one Spirit.
Ephesians 1:13 (LEB) — 13 in whom also you, when you heard the word of truth, the gospel of your salvation, in whom also when you believed you were sealed with the promised Holy Spirit,
and the context of the verse you quote
Ephesians 4:3–6 (LEB) — 3 being eager to keep the unity of the Spirit in the bond of peace; 4 one body and one Spirit (just as also you were called with one hope of your calling), 5 one Lord, one faith, one baptism, 6 one God and Father of all, who is over all, and through all, and in all.
references the spirit and the body
it is 1cor 12:13 which relates the spirit and the body Spirit baptism placing us in the body
otherwise
Hebrews 6:2 (LEB) — 2 teaching about
baptisms and laying on of hands, and resurrection of the dead and eternal judgment.
there are plural baptisms
Nope, I didn't ignore any verses. Faith does indeed exist without water baptism. But the faith that brings about salvation does not. The faith that brings about salvation MUST conform to what God says will bring about reception of His gift.
You ignored many
all noted salvation apart from water baptism
