The Trinity in Isaiah

This sermon examines the doctrine of the Trinity through specific passages in the book of Isaiah, identifying the distinct roles and relationships of the Father, Son, and Holy Spirit. The analysis begins with Isaiah 42, where the Father is presented as the commissioner who delights in the Son, the Servant, who is empowered by the Holy Spirit to bring gentle justice to the Gentiles. The teaching continues with Isaiah 48, exploring the debate over whether the Father or the Son is the speaker, while emphasizing the unity of the divine persons in the sending of the Messiah. Finally, the sermon introduces Isaiah 61 alongside Luke 4, highlighting the anointing of Christ by the Spirit to preach good tidings and bind up the brokenhearted. Throughout the discussion, the preacher emphasizes that the three persons of the Trinity are united in purpose and authority, rather than operating in a hierarchy of subordination, providing a cohesive Old Testament foundation for understanding the triune nature of God.
