In this episode of the Cold-Case Christianity podcast, J. Warner Wallace tackles one of the most controversial and misunderstood doctrines in the Christian worldview: the Trinity. Drawing on his experience as a cold-case homicide detective, J. Warner treats the identity of God like a crime scene, building a suspect profile from Scripture and then asking: Who actually fits the evidence?
J. Warner explains why the word “Trinity” doesn’t need to appear in the Bible for the doctrine to be thoroughly biblical, how the classic attributes of God (omniscience, omnipresence, omnipotence, eternality, immutability, Creator and Sustainer, and the sole object of worship) apply not only to the Father, but also to the Son and the Holy Spirit, and why this forces us to a triune understanding of God if we’re going to be honest with the text. He also explores why groups like members of the LDS Church, Jehovah’s Witnesses, and Oneness Pentecostals—who may claim to believe in Jesus—still fall outside historic, orthodox Christianity when they deny the triune nature of God.
Along the way, J. Warner offers a clear, working definition of the Trinity (“one what and three whos”), warns about common heresies like modalism and Arianism, and shows how the earliest creeds and confessions weren’t inventing new ideas but summarizing the best inference from biblical data. This episode will help you clarify your own thinking, disciple your kids and students, and confidently engage missionaries and friends who say, “We’re Christians too,” while rejecting the Trinity.

It blows my mind that so many people can read the Bible and still believe in a trinity. Is it evidence of the underlying broken state of humanity? I would say “why doesn’t God just set the record straight?” but then, it’s pretty clear in the Bible, when you have “The Son” saying things like “The Father is greater than I am” such that I wonder how much clearer the bible could be.
