5: SARDIS 1517-1820 AD
“And unto the angel of the church in Sardis write; These things saith he that hath the seven Spirits of God, and the seven stars; I know thy works, that thou hast a name that thou livest, and art dead. Be watchful, and strengthen the things which remain, that are ready to die: for I have not found thy works perfect before God.” Revelation 3:1, 2
Sardis means ‘what remains’, and we see Jesus saying that there were still some good things remaining in this church, but they needed to be strengthened. This is the time of the Protestant churches that grew out of the reformation.
