The objection
Many letters mention only God the Father and Jesus Christ in their greeting. Nor does there seem to be a separate throne for the Spirit beside the throne. Was his deity added only later?
1. Silence has evidential force only under one condition
An omission refutes a doctrine only if the text in question would have to list all relevant persons exhaustively. A letter's greeting has no such function. It names the source of blessing in a particular form; it promises no exhaustive treatise on God's inner life.
Romans already shows the argument's limit. The greeting names Father and Son, while chapter 8 extensively characterizes Christians' life through God's Spirit. One cannot read out of the shorter greeting what the letter later expressly unfolds.
2. Other benedictions explicitly name the Spirit
The closing benediction of the second letter to the Corinthians connects Christ's grace, God's love and the fellowship of the Holy Spirit. The differing forms of greetings therefore show no early agreement on excluding the Spirit. They show different ways of addressing the same saving action.[1]
Moreover, Father, Son and Spirit are not interchangeable in their mission. That the Spirit points to Christ and leads the church into fellowship with the Father explains a different thematic emphasis without requiring an inferior nature.
3. Visions speak in images
In Revelation 5, Christ appears as a slain Lamb. No one should conclude from this that his human form consists of seven horns. Likewise, the absence of a third piece of seating cannot decide the Spirit's deity. A throne image does not arrange three divine bodies spatially alongside each other.
The seven spirits before the throne, the lamps and the Lamb's seven eyes are often understood as portraying the fullness of the divine Spirit. Other interpretations see heavenly spirits. The symbolism must be interpreted; it is neither a simple counterargument nor a self-explanatory proof of personhood.
4. Doctrine is determined by evidential force, not frequency of mention
The Spirit knows God's depths, dwells as divine presence in the church and acts as the giver of life. These statements do not become false when another passage does not expressly name him. Nor does Christ's full humanity depend on every greeting mentioning it.
The objection confuses frequency with ontological rank. The differing presentation of the persons belongs to the biblical witness. Their deity must be assessed by what the texts actually say about them.
5. Does a later doctrinal clarification prove a later invention?
That the Spirit was debated for a long time initially shows difficulty in receiving and explaining the scriptural witness. It does not prove that this witness arose only during the debate. Two times must be distinguished: when a statement is present in the apostolic writings and when the church expressly establishes its meaning against a particular objection.
Basil grounds his defense of the Spirit precisely in Acts 5, 1. Corinthians 12 and the baptismal formula. He discusses why the Spirit must not be placed as a servant beneath Father and Son.[2] These arguments must be examined against the biblical text; their later ecclesiastical use makes them neither true nor false. The answer to a less detailed early formulation is therefore precise exegesis of the existing statements, not the mere date of a later doctrinal decision.
