Um . . .

Gary . . . YOU were the one who broached the "begotten" issue . . . so that kinda determines that "begotten" is the issue to be stuck on.
Her question is WHAT do think is meant by "begotten"?
Cause if this:
Is really how you feel . . . then you cannot use the "begat" arguement against a Trinitarian understanding of the Godhead . . . because you don't even understand what He means . . . ergo, if you don't understand what He means . . . then how can you say what He means contradicts Trinity?
You can't.
SO . . . if you think that the term "begotten" mitigates AGAINST Trinity (which is what you have been arguing) then you MUST therefore have an opinion on WHAT begotten means or entails. THAT is what she is asking.
To claim that you don't know because God doesn't tell us is essentially to refute your own line of reasoning . . . and therefore you must give up the arguement that it contradicts Trinity.
BUT, God does indeed tell us what and begotten means (per the Greek usage) and HOW Jesus is such.
Yeah in English . . . but we are not talking about English.
We are speaking of Greek and Greek has a different meaning. Like David . . .
Ps 89:27
27 "I also shall make him My firstborn,
The highest of the kings of the earth.
NASU
who was certainly not the "offspring" of God. The term is OFTEN used in the sense of preeminance . . . as it is here.
and
Ps 2:7
7 "I will surely tell of the decree of the LORD:
He said to Me, 'You are My Son,
Today I have begotten You.
NASU
where David (or Israel) is certainly not the "offspring" of God.
These are proofs of the wide range of ancient concepts held within the statements. It does not need to literally mean "offspring."
Otherwise your ridgid interpretation means God had sex with Mary . . . perhaps you should then become a Mormon?
