Definition
Sonship (Greek: υἱοθεσία huiothesia) refers to the position and destiny of believers as children and sons of God. In the corpus it is one of the most charged concepts: it surpasses the starting point of childhood (new birth) and points to the eschatological maturation toward full conformity to the Son. Three distinct emphases: transformative destiny (Noordzij), corporate eschatological fulfillment in the Manchild (Jones), and manifestation of the sons of God as eschatological climax (Warnock).
Usage in the Corpus
Cees Noordzij
Sonship is for Noordzij the central soteriological category, connected to huiothesia (Rom. 8:15, 23; Gal. 4:5). It is not merely the legal status of being God’s child but the transformative becoming-into-conformity-with-the-Son: the child of God grows toward the measure of the mature Son. The manifestation of the sons of God (Rom. 8:19) is the eschatological goal of the entire creation. [Noordzij, Moses and the Way to Sonship, §3]
Stephen Jones
Jones connects sonship to the corporate Manchild (Rev. 12): the firstfruits who are fully formed into the image of Christ together constitute the corporate Son who is caught up to the throne. Sonship is corporate in Jones: not individual but as a body of overcomers who reach full maturity. [Jones, Creation’s Jubilee, Ch. 5]
George Warnock
Warnock speaks of the “manifestation of the sons of God” (Rom. 8:19) as the soteriological climax to which the Feast of Tabernacles fulfillment leads. The sons of God are the overcomers who maintain and advance the kingdom of God.
