The notion that angels married women before the Flood and produced giants is unfounded. Angels do not marry, as Jesus clearly states that in the resurrection, humans neither marry nor are given in marriage, but are like angels of God in heaven. Angels, being spirit beings, cannot cohabit or reproduce with women, who are human beings. These are two different kinds of beings, and kind reproduces only after kind, adhering to God's strict law established from the beginning. Furthermore, while angels are sometimes called sons of God, they neither marry nor are given in marriage, reinforcing that the sons of God mentioned in the context of these marriages were not angels but human beings.

A significant point against the notion that the sons of God in Genesis 6 were fallen angels who married human women is the fact that angels cannot reproduce. Jesus Christ teaches in Mark 12:25 that in the resurrection, human beings will be like the angels in heaven, who neither marry nor are given in marriage. This statement clearly contradicts the idea that angels could engage in marital unions with the daughters of men as described in Genesis 6:2. Since angels do not marry, they cannot produce offspring, refuting the interpretation that they fathered the mighty men of renown through such unions.

Angels do not marry, cannot have sexual relations, and according to Scripture cannot die. This truth stands in direct contrast to depictions in which angels desire to become human and enter marriage. Holy angels have no such inclination, whereas any desire to assume human form would belong only to fallen angels. The point emerges from Jesus' statement in Luke 20:34-36 that the sons of this age marry and are given in marriage, yet those counted worthy to attain the resurrection from the dead neither marry nor are given in marriage, for they are equal to the angels and are sons of God. The passage thereby identifies angels as spirit beings whose nature excludes the marital and reproductive relations that belong to physical humanity. This distinction reinforces the broader chronology of angelic creation and function: angels were formed as individual spirit servants before the recreation of the earth, remained loyal or fell according to their own choices, and now minister under God's direction to those who will inherit salvation. Because they occupy a different order from resurrected humans, they neither require nor possess the capacity for marriage, underscoring their appointed role as ministering spirits rather than participants in the family relationships reserved for the children of God.
