Boyd: a broken Trinity?

Pastor Greg Boyd, on the theme of Jesus being forsaken by the Father (and Spirit?) on the cross:

If God’s eternal essence is the perfect love of the Father, Son and Holy Spirit, as I believe, then any suggestion that this perfect love was severed, even for a moment, would, by definition, entail that God ceased to exist. Such a conclusion is, to my way of thinking, a logical impossibility.

See the whole post for his creative answer. On the forsakenness theme, also this and this.

To the extent I understand Boyd’s view of the Trinity, he’s a three-self theorist, and he thinks the three perfect persons are one God because they eternally enjoy a perfectly loving relationiship. That seems like a non sequitur though. Why wouldn’t we have instead three gods who are ideally close friends?

Interestingly, in a footnote at the end of his post, he notes that some friends believe his view is both kenotic and tritheistic, and so is unorthodox on two counts. At first glance, at least, both do seem to follow… Has he addressed these issues anywhere recently?
