A good way to get at the issue from the Reformed standpoint, is to go back to the Reformed Scholastics, a prince of whom (which we can access fairly easily) is Francis Turretin,

prolegomena (i.e. preliminaries) on the distinction between
archetypal and
ectypal theology: that is, the distinction between theology as God knows it (as God knows himself), and how we know God-revealed.
Richard Muller surveys Reformed theology from the Reformation through the post-Reformation period--really all the way up to the age of Westminster--in his Post-Reformation Reformed Dogmatics volumes (review here:
https://www.monergism.com/legacy/mt...reformation-reformed-dogmatics-richard-muller). It is hard to overestimate the utility of these volumes, when it comes to helping us see what is really packed into our Confessional commitments on paper. The tendency is to interpret what has been bequeathed to us apart from the theology that bore it as fruit, thus pouring our own meanings into the words that were first intended as the distillation of over 150yrs of ferment.
Muller helps on this question of "analogy" also. John Bugay's recent posts seeks to show (

http://triablogue.blogspot.com/2016/04/thomas-train-wreck-and-analogia-entis.html) how the terminology "analogy" comes to us mediated through Aquinas; but despite the term's continued employment even into the Reformation era, our theologians jettisoned significant assumptions once tied to it.
Bottom line: it isn't equivocal to use that which God has accommodated to man's limitation as vehicle for truth-conveyance concerning itself, and to accept what he "lisps to us" (Calvin's expression) as perfectly true, even if not ideally true (that is to say, Truth unmediated).
