a trinity of Jesus

As a follow-up to the Capon quote:

"Therefore, though it is indeed God The Son, the Second Person of the Trinity, who becomes incarnate in Jesus, there isn't any of the Trinity outside him.
The Father and Spirit coinhere in everything he says and does"
-Capon, Hunting the Divine Fox, p. 87, emphasis mine


Check out the painting, "Holy Trinity," by
Fridolin Leiber...which Chrisopher Orczy innocently posted on his computer desktop, only to be informed by his friends it was "heretical."

Why?

"It must be to do with the fact that all three persons are depicted as Jesus."
