"Behold, the Child is Father to the Man"

An earlier version of the comments I make below appeared only moments ago as Comment Number 7 at this link, which you are invited to visit: 

My own father used to call me, endearingly, daddy (= "Wuora") -- as though I was the very one I was named after. I never flinched at that, I don't think. It's the custom. Many fathers did, but they're a dying breed. I didn't see any paradox there. I don't do that myself, tho. For years I have thought that it was Jesus who (or some 'hid' part of the bible which) famously said something like: "Behold, the Child is Father to the Man." But it seems that Wordsworth, whom I read for the first time decades ago but have come upon too infrequently as Time has flown, was a true original with that enduring line - inspired by a rainbow.

"So that the father is also, in his own right, the child."
