The Revelation of the Father
John 14:7–11 presents Christ's claim that knowledge of the Son is knowledge of the Father, and that the Father dwells in the Son and the Son in the Father — a claim no mere creature could make. The sermon works through three confirmations of this unity: the nature of the Son (his consubstantiality with the Father), the words of the Son (which are the Father's words by virtue of shared essence, not mere instrumentality), and the works of the Son (which the Father performs through the Son as one divine operation). The Trinitarian theology at stake is not speculative — it is the doctrinal ground upon which the disciples, and all believers, stand when the world collapses in on them, because the Son who is God of God, light of light, very God of very God, is the one who came down 'for us and for our salvation.'
The Great Commission
Christ's Great Commission in Matthew 28:18–20 provides the church with her complete marching orders: go, make disciples, baptize those disciples, and teach them to observe all that Christ commanded. The authority behind the commission belongs to the risen and exalted Christ, who possesses all authority in heaven and earth; the assurance sustaining it is His promise of perpetual presence to the end of the age. The sermon treats the specific focus of the commission in sequence, defending believers' baptism by immersion as the pattern demanded by the text and the order it establishes — make disciples first, then baptize — against both baptismal regeneration and paedobaptism. The Trinitarian formula of baptism occasions an extended treatment of theology proper, including divine simplicity, impassibility, and the unity of essence in three persons, with warnings against tritheism, modalism, and subordinationism.
