Of which all are partakers (ἧς μετοχοι γεγόνασι πάντες)
Rend. “of which all have been made partakers.” For μέτοχοι partakers see on Heb 3:14. All, that is, all sons of God.
Bastards (νόθοι)
N.T.o. See Wisd. 4:3. They might think that they would not suffer if they were really God's sons; whereas the reverse is the case. If they did not suffer, they would not be God's sons.
