John Trapp on Revelation 1:18

Verſe 18. That liveth and was dead] So can every regenerate man ſay, Luk. 16.32, Epheſ. 2.1. See the Note there. All Saints are heirs of the grace of life, 1 Pet. 3.7.

And have the keyes] The Pope therefore is not key-keeper, as he falſly boaſteth; telling us, That God hath put under his feet the beaſts of the field, the fowls of the air, and the fiſh of the ſea: that is (as he interprets it) all the ſouls in earth, heaven, and purgatory.
