Charlie recently offered a posting on the Trinity (don't miss Tom's comment to that post either). I had been working on one concerning practical ways of applying the Trinity so that follows below. Generally, the Trinity is considered one of the more (perhaps, most) esoteric and abstract Christian doctrines. To test the relationship between doctrine and practice, we might as well see what, if any, practical difference the doctrine of the Trinity might make in our lives. Besides, in one of Millard Ericksonâs books (it was on the Trinity), he comments that Kant thought the Trinity the epitome of meaningless, impractical Christian doctrine â and who can resist giving it to a hoity-toity philosopher who canât possibly respond or find out where I live?
