Friends, today we come to Trinity Sunday, which has been called “the preacher’s nightmare.” But as you probably know from previous sermons of mine, I don’t agree with that at all. I think every Sunday is Trinity Sunday. The Trinity names what is most fundamental and basic in our whole theology and spirituality, and we should rejoice in talking about it! Today, let’s look at the Trinity through three lenses: the words of Scripture, an analogy from St. Augustine, and the viscerally real “so what” of salvation.
