Revelation 3:1 To the angel[a] of the church in Sardis write: These are the words of him who holds the seven spirits[b] of God and the seven stars. I know your deeds; you have a reputation of being alive, but you are dead.
And these as well.
Revelation 2:1 To the angel of the church in Ephesus write: These are the words of him who holds the seven stars in his right hand and walks among the seven golden lampstands. 2 I know your deeds, your hard work and your perseverance. I know that you cannot tolerate wicked people, that you have tested those who claim to be apostles but are not, and have found them false. 3 You have persevered and have endured hardships for my name, and have not grown weary. 4 Yet I hold this against you: You have forsaken the love you had at first. 5 Consider how far you have fallen! Repent and do the things you did at first. If you do not repent, I will come to you and remove your lampstand from its place.
It seems that just speaking Greek isn't any guarantee.
Sardis & Ephesus?
Sardis & Ephesus went off the rails REALLY quickly!
Damned poor catechism is EVERYWHERE!!!
