Book excerpt: There are few beliefs more essential to Christianity than that of the Trinity. Millard Erickson seeks to provide a lucid and judicious answer to the question: Is Jesus eternally subordinate to the Father, or is Jesus equal with the Father? In addition to providing rigorous theological analysis of that question, Erickson exposes flaws in familial implications derived from the Trinity. This increasingly debated topic has finally received a thorough, careful, and objective treatment.
