For I am persuaded, that neither death, nor life, nor angels, nor principalities, nor powers, nor things present, nor things to come,

Ambrosiaster
AD 400
These are all the things which have come upon us since we were abducted by the devil. Paul lists them in order to steel us against them if they should appear so that, confident of the hope and help of Christ and armed with faith, we might be able to fight against them. Commentary on Paul’s Epistles.
Paul says that he is sure, not merely that he is of the opinion … that neither death nor the promise of temporal life nor any of the other things he lists can separate the believer from God’s love. No one can separate the believer from God; not someone who threatens death, because he who believes in Christ shall live even if he dies, nor someone who offers earthly life, because Christ gives us eternal life. An angel cannot separate us, because “if an angel comes down from heaven and tells you something other than what you receive, let him be anathema.” Nor can a principality, i.e., an opposing power, because Christ has … vanquished them in himself.
"Creature "is synonymous with activity, being our work, and such activity "shall not be able to separate us from the love of God, which is in Christ Jesus our Lord."
