Maybe it is wise to skip analogies for the Trinity altogether? My husband was just saying that the common "H2O= ice, water, steam" one is sort of modalism. Maybe the best thing is to try and present God without non biblical attempts to explain Him. And understanding marriage as Christ and the Church ought to be good enough for us.
Yes, I think it is wise. One of the interesting things about studying those who had to battle early Trinitarian heresies is that they believed that the Trinity was something to be adored and worshiped more than trying to penetrate it. They even spoke in terms of daring to have to speak in ways they might otherwise avoid because troublers of the Church were denying the divinity of Christ and so they had to take up the use of words to exclude those who would deny the truths that had been received in the Apostolic faith.
I was thinking about this the other day that we don't typically engage in "analogies" for things we don't understand. It is sufficient for us to know that the sun provides light and heat for us. Those with a deeper understanding of nuclear physics understand the nature of fusion and how enHydrogen atoms fuse to produce energy in the form of heat and light. We don't think: "I think I'll create an analogy for how the Sun produces its light..." and then embark upon a form of pseudo-technical language to describe a process we don't quite grasp because we lack the training to properly apprehend it.
I think it's best for us to simply confess what we've received - the Nicene Creed and Definition of Chalcedon. We may not understand it at a technical level but, if it's not our discipline, then why do we feel compelled to think that analogies that we can "relate" are adequate.
Let us simply adore the One God in Three Persons. Let us confess what the Church catholic has confessed for centuries and meditate upon it and grow in our understanding and not make fools of ourselves in trying to "creatively" deceive ourselves, our children, or others with analogies that are dangerous. I think it is better to remain devotionally ignorant of certain things and strive to grasp them further than to set our minds down a dark path with analogies.
