“...what difference...”
It would matter because of the hypostatic union and Jesus’ nature as true God and true man. If He were to have children, they would be partly divine in a watered down sense as Jesus’ human nature (from his Mother) and His Divine Nature (from the Holy Spirit) are not separated out. The idea that His children would be part God is just not acceptable and, as a Person of the Trinity, He was well aware of this and Our Lord remained celibate.
Thanks. ( I don’t know. I would think that the Creator of the entire universe could handle any problem like the natures of any children. Especially since He not only controls the process for each of us ( joining of specific soul of H creation and choosing with corporeal body) but also because of all the evidence He can modify Hjs usual recipe or process for children at any time He wishes — indeed miraculous or unusual or unexpected births are almost a trademark of the Biblical God. So even if we agree that “1/4 divine” children would be “ unacceptable” to us both, it doesn’t necessarily follow that such would be the result. God is all - powerful and He has made it clear He is in control of the generative business. I’ve full faith He could have worked out the 1/4 question. Just the peramblings of a layperson here, though. Just picking up on the original posting is all. I’ve no particular long in this race, ha. But thanks for your interesting comment. Much appreciated.
