The Father begat the Son. The Father is not the Son. The Father did not beget the Father, nor the Son beget the Son. Nor did Father, Son, and Spirit beget the Father, Son, and Holy Spirit. I can think of only two ways your statement could be accurate: 1. Modalism, which is largely viewed by Christian theologians as misguided in its most innocent form or heresy in its worst. 2. Your statement is using "God" as an overloaded operator and would be better read "God (the Father) somehow begat [God (the Son)]". The second is nonsense because it condemns Mormons for the same kind of thinking (which can't be the case in the Brigham Young context). The first isn't viable because that's not what the majority of Trinitarians believe. It can come back into play if it can be shown that while the majority don't believe it today, it was in fact, what Trinitarian Americans believed in the mid- to late 19th century. Which brings us back to Maureen's call for citations.
