For I am persuaded, that neither death, nor life, nor angels, nor principalities, nor powers - whether good or bad. But as the bad are not called “angels,” or “principalities,” or “powers,” save with some addition to show that such are meant (Mat 25:41; Col 2:15; Eph 6:12; 2Pe 2:4 - except perhaps 1Co 6:3), probably the good are meant here, but merely as the same apostle supposes an angel from heaven to preach a false gospel. (So the best interpreters).
nor things present, nor things to come - no condition of the present life and none of the unknown possibilities of the life to come.
