What would be a way to use Apophatic Theology to define the Trinity?

Is there a reasonable way to use all the various heresies as defined by the various ecumenical councils and declarations of the pre-2nd millennium church (0AD-1000AD), or other sources from this time period, to define what the Trinity is using Apophatic Theological methods? Obviously scripture does include some Cataphatic statements, but please try to focus on Apophatic methods.
