The Seed of Angels

In Genesis 6 it says that the sons of God took women as wives and giant (Nephilim) children.

This begs the question: "Wait... can angels reproduce?"

1 Corinthians 15:38-41
But God gives it a body just as He wished, and to each of the seeds a body of its own. 39 All flesh is not the same flesh, but there is one flesh of men, and another flesh of beasts, and another flesh of birds, and another of fish. 40 There are also heavenly bodies and earthly bodies, but the glory of the heavenly is one, and the glory of the earthly is another. 41 There is one glory of the sun, and another glory of the moon, and another glory of the stars; for star differs from star in glory.

The passage 1 Corinthians 15:38-41 makes the following claims:

• For every type of body, there is a physical and a spiritual aspect
• Every type of body (creature) has its assigned "seed" (gene, semen, DNA)
• God assigned each seed to each type of body and created them to be separate
• The glory of heavenly bodies differs from earthly ones
• Heavenly glories differ from each other (sun, moon, and individual stars)
• The sun, moon, and stars are bodies (The Celestial Connection)

If everything that has a body has an assigned seed by God, then heavenly bodies have their own seed.

"But what about Luke 20:34-36? Jesus says that humans can't marry in heaven because angels can't marry!"

That is simply not true.

Luke 20:34-36 quotes Jesus answering the question of Sadducees.

They ask if a woman has multiple husbands in life (each dying before she remarries) then who is her husband when she is resurrected (in heaven).

Luke 20:28-33
and they questioned Him, saying, “Teacher, Moses wrote for us that if a man’s brother dies, having a wife, and he is childless, his brother should marry the wife and raise up children to his brother. 29 Now there were seven brothers; and the first took a wife and died childless; 30 and the second 31 and the third married her; and in the same way all seven died, leaving no children. 32 Finally the woman died also. 33 In the resurrection therefore, which one’s wife will she be? For all seven had married her.”

Jesus replies with a famous few verses that people often misunderstand.

Luke 20:34-36
Jesus said to them, “The sons of this age marry and are given in marriage, 35 but those who are considered worthy to attain to that age and the resurrection from the dead, neither marry nor are given in marriage; 36 for they cannot even die anymore, because they are like angels, and are sons of God, being sons of the resurrection.

Jesus starts by pointing out that not everyone gets to heaven, and that those who do will not marry and are not given in marriage.
He then says why: "for they cannot even die anymore, because they are like angels, and are sons of God" (Luke 20:36 NASB).
The commas are placed there for a reason. He says that they cannot die because they are like angels. He does not say that they cannot marry because they are like angels.
Regardless people use this verse to "prove" that angels cannot marry and cannot have sex.

It clearly does not say that. It says that angels cannot die. The implication is: if we do not marry in heaven because we live forever and angels live forever as well, then they do not marry either. That logic is accurate, but there is a big difference between DO NOT and CANNOT. They clearly can because they do so with human women in Genesis 6. This was, however, a grave sin and God punished them for it (Jude 1:6-7, 2nd Peter 2:4-6). It's also worth noting that there are no female angels, so who would they marry in the first place?

The point that Jesus is making in Luke 20 is that in heaven there is no place for the role of marriage, and therefore the question they are posing is flawed in its conception.

1 Corinthians 15:38-41 clarifies the differences between heavenly and earthly creatures and that all of them have seeds as God intended. Why God intended for angels to have seed? We simply do not know. The word doesn't say. But it does say that it was "as He wished" so either he had a purpose in mind or it was simply for consistency. Whatever the case, they clearly have seed and the ability to use it, per God's design.
