The seven spirits are seven angels, but they are neither equal in honor nor coeternal as to be included to the Holy Trinity, but as genuine and faithful slaves. For the prophet says to God, “For all things are slaves of yours.(Ps. 118:91)” In all things the angels are included too. Also the same prophet says concerning them, “Bless the Lord, all his host, his ministers doing his will.(Ps. 102:21)” Likewise, the apostle mentions to Timothy when writing the first letter, “I charge you before God, and Christ Jesus, and the elect angels.(1Tim. 5:21)”
