Paul was alluding to the liturgy of Baptism, where the recipient (regardless if they were immersed or not) is symbolically submerged in water as a body is buried in a grave, only to rise again to a new life with God.
It is apparent that you and I have radically different ideas of the mind of Paul, when he was writing in Romans 6 about the relationship between Christ and baptized believers … that is, between Christ and the church … which ultimately is Paul’s topic, not the ‘liturgy of baptism’.
Let’s explore what Paul had to say, and let’s have Scripture interpret Scripture.
First, you may recall that the church is occasionally referred to as the Bride of Christ. Jesus is the Bridegroom, the church His Bride. Paul wrote explicitly about that relationship in his letter to the Ephesians (Eph. 5:25-30). This passage is pretty specific, but to be sure there is no misunderstanding, in v.31 Paul quotes from the Genesis account (Genesis 2:24 – God’s standard for marriage); then in v. 32 he confirms the significance of the passage in his context: “I am saying it refers to Christ and the church.”
So in Paul’s understanding, a man and a woman come together in marriage, and as husband and wife they are joined together in an inseparable unity. They’re together in everything, through thick and thin … which Paul then applies equally to Christ and His Church. Through baptism into Christ, we come together in the same way, and just like a bride and groom, we unite together with Him in an inseparable oneness – for better, for worse, for richer for poorer, in sickness and in health, till death do us …
No!!! Not even Death has the power to separate us from Christ! And this is precisely the point Paul makes in Romans 6 when he talks about being baptized into Christ. Our unity with Christ is so permanent that it survives everything, including death. (Not that death is the only important thing, but we cannot ignore the fact that our union with Christ is so all-encompassing that sharing in His death is an unavoidable part of the whole package.)
In his first letter to the Corinthians, written about a year earlier, Paul had more to say about this baptism (I Cor 12:12-27). Read the whole passage for a fuller understanding, but three points stand out:
(1) In this union with Christ, we never lose our personal identity. There is no hint in Paul’s writing that we’re swallowed up by, absorbed into, or immersed into this body of Christ. We are, each of us, separate and individual parts of the Body. We retain our personal identities. (vv.12, 14, 27)
(2) We are baptized by the One Spirit into the One Body of Christ Jesus. (v.13) There’s the same phrase as in Romans 6:3, but amplified for us. It is the Holy Spirit that produces this union. The Holy Spirit, working in and through us, points us to Christ, draws us to Christ, and joins us to Him. That joining process, executed by the Spirit, is our baptism into Christ. Paul says nothing at all about the “liturgy of baptism”. As a sacrament, his comments are directed entirely to the inward and spiritual grace, not the outward and visible sign.
(3) A point that he develops further in Romans 6 is that, if one part of the body suffers, we all suffer. (v.26) In Romans 6, he reaffirms the idea that, as Christ suffered and died, so because we have been baptized into His body, we all suffer and die. His death becomes our death. We die to sin, and the power that sin once held over us; and we die to the old self, and the lusts and passions that once drove us. This all happens on a spiritual level, as we are empowered by the Holy Spirit. Paul is not in the least concerned about the “outward and visible” aspects of baptism … the liturgy of the church ceremony. He uses the outward and visible, the earthly and familiar, like marriage between husband and wife, and a body with many parts, to describe the inward and spiritual baptism into Christ. This is the subject of his continued teaching.
As a sacrament, baptism is the outward and visible sign of an inward and spiritual grace. That grace, that “undeserved gift from God” which Paul tells us is the important part of baptism, is specifically the indwelling of all believers by the Holy Spirit, and our complete union with Christ which necessarily results. Of course, that even includes a spiritual “death and resurrection” as an incidental part of the much larger picture. But to limit the interpretation of baptism to this one aspect exclusively is to miss the major thrust of Paul’s teaching on the subject. He wants us to recognize the full measure of what it means to be baptized into Christ.
And so, in sacramental churches today, our baptismal liturgy is designed as the outward and visible sign, not merely of death and resurrection, but of the inward and spiritual gift, the indwelling Holy Spirit, poured out on all believers.
It was not until a couple of centuries ago, with the advent of denominations that dismissed the sacramental aspect of baptism, and it became merely an ordinance of the church, that the focus then shifted from the gift of the Holy Spirit to “burial and resurrection” as the primary significance of baptism. It was not always so.
