Love, for example. To be honest, no matter what I might say on the subject would be inadequate. But any definition is unsatisfactory. Words will never do a kiss justice. Try one more.

You and I both know that anything we might say would be inadequate. What brings the subject to mind are the familiar words of the traditional Trinitarian benediction which we heard in the lesson, a text chosen because on the liturgical calendar today is designated Trinity Sunday. That deserves note if for no other reason than that this is the only Sunday in the long church year that is set aside to focus on a doctrine. Plus, as you Bible scholars well know, the word Trinity never once occurs in the pages of scripture. I will tell you why.
