Before his birth, did Jesus exist only in God's plan?

1. Predestination is not already personal preexistence

A plan can exist before the planned person is born. 1. Peter 1,20 distinguishes foreknowledge and historical manifestation. We must therefore not immediately infer a conscious earlier existence from every “before.”

What matters is which verbs and relationships the particular text names. Is something decreed, or does someone already act and stand in a personal relationship? A uniform label for all texts cannot replace this question.

2. John 17 speaks of glory possessed with the Father

Jesus asks for the glory he had with the Father before the world existed. The statement connects prior possession with a personal counterpart. Verse 24 adds the Father's love for the Son before the foundation of the world.

One can attempt to read both statements exclusively as an anticipated plan. But one must then explain why the text uses the language of already existing shared glory. The possibility of anticipatory speech elsewhere is not yet evidence that precisely this manner of speaking occurs here.

3. John 1 connects the Logos with all things' coming into being

The Logos is already present in the beginning; everything that came into being arises through him. In verse 14 this Logos becomes flesh. The text's movement thus leads from the Logos before the world to incarnation, not from an abstract design to a previously nonexistent bearer.^[3]

Colossians 1, too, places Christ before all things and connects their existence with him. A shared explanation of these texts must achieve more than a possibly metaphorical understanding of an individual sentence. It must explain the consistent connection between being before the world, creative action and incarnation.

4. The conversation partners must be carefully distinguished

The Biblical Unitarian self-description cited here places the beginning of Jesus' life in God's activity in Mary.^[1] Christadelphian confessions have their own doctrinal profile and must not be equated with it in every detail.^[2] Nor is “Socinians” an interchangeable name for every present-day group.

For the question of Jesus' existence before the world, the specific thesis of mere existence in a plan remains decisive. It can explain individual statements of predetermination. As an overall explanation of the Johannine texts, however, it falls short of their personal language and theology of creation. The Son is not merely God's realized thought about a human; he is the Logos who became human.

5. “The Father alone” and “the Spirit as power”

Biblical Unitarianism and Christadelphianism each have their own doctrinal profiles.^[1][2] Their claims decisive here must be examined individually. “One God, the Father” in 1. Corinthians 8,6 does not entail that only one person can be divine. Otherwise, by the same exclusion procedure, “one Lord, Jesus Christ” would have to deny the Father's lordship. The decisive addition is: All things are through Jesus Christ. Paul distinguishes Father and Son within the description of the work of creation; he does not place Jesus among its results.

Nor is “Spirit” invariably another word for impersonal power in the New Testament. In John 14–16 Jesus distinguishes the other Advocate from himself and the Father; in 1. Corinthians 12,11 the Advocate acts according to his will. The possibility of personification is insufficient to explain the consistent relationships of sender, sent one and witness as a mere figure of speech. An overall explanation must therefore answer three questions: Who creates, who was with the Father before the world, and who knows, wills and bears witness? The model “a human Messiah in God's plan and an impersonal power” does not do justice to these statements.

6. The Socinian objection to two natures

The Racovian Catechism formulates the objection more sharply than a mere reference to Jesus' humanity: Divine and human attributes are opposites; their union in one person is therefore contradictory. Moreover, each of the two complete natures already constitutes a person.^[4] The second claim, however, is an additional metaphysical assumption. It is not proved by the first.

A contradiction would exist if Christ were simultaneously created and uncreated in the same respect. The Christian statement is more precise: The eternal Son possesses the uncreated divine nature and has assumed a created human nature. It asserts neither that his humanity is uncreated nor that his deity is a creature. The natures are not identified with one another. John 1,14 attributes becoming flesh to the already previously existing Word: The same personal subject enters a truly human life. The text thus offers a reason to distinguish the agent from the modes of his existence.

This does not exhaustively explain how the unity of both natures exists. But it shows why the alleged formal contradiction does not follow. Anyone equating every complete human nature from the outset with a second, independently existing person already excludes incarnation through their definition. They must first justify this premise rather than presenting it as the result of biblical examination.
