With regard to your article and the question that this thread was founded on I would just like to say that it is almost unbelievable that Evangelicals as a whole do not understand that the very simple answer to this is:
No, the Trinity was not broken, it is not possible.
No, the Son was not separated from the Father, it is not possible.
Now, if someone teaches to the contrary (and believe me, almost all "independent Evangelicals" teach this), then they cannot be considered Trinitarians according to the Historic Christian faith, nor do they hold to a Chalcedonian understanding of the incarnation. As has been said (perhaps by Matthias), if that is the case, they should own it. The reason they don't I believe is basically two fold:
1. They believe they do hold to the historic Christian faith regarding the Trinity and the incarnation.
2. The reason they don't understand that they teach neither (regarding #1) is ignorance.
Whether someone takes issue with these doctrines of the historic Christian faith has no bearing on whether teaching that the Trinity was broken during the crucifixion, it is two different issues. Civic, how do the people you share this with take it, what is there attitude. I have had two pastors I know become angry although they refuse to discuss it.
