Note his first comments to the first of the seven churches mentioned in Revelation chapters 2 and 3:
1 “To the angel of the church in Ephesus write: ‘The words of him who holds the seven stars in his right hand, who walks among the seven golden lampstands. 2 “‘I know your works, your toil and your patient endurance, and how you cannot bear with those who are evil, but have tested those who call themselves apostles and are not, and found them to be false. 3 I know you are enduring patiently and bearing up for my name’s sake, and you have not grown weary.
But don’t get smug or arrogant. There’s more.
4 But I have this against you, that you have abandoned the love you had at first. 5 Remember therefore from where you have fallen; repent, and do the works you did at first. If not, I will come to you and remove your lampstand from its place, unless you repent.
So don’t forget the love.
Then there’s this. So Jesus has things He hates? Who knew?*
6 Yet this you have: you hate the works of the Nicolaitans, which I also hate. 7 He who has an ear, let him hear what the Spirit says to the churches. To the one who conquers I will grant to eat of the tree of life, which is in the paradise of God.’
Apparently the Nicolaitans were seducing Christians with idolatry and sexual immorality — much like the theological Liberal churches today.
Revelation 2 14 But I have a few things against you: you have some there who hold the teaching of Balaam, who taught Balak to put a stumbling block before the sons of Israel, so that they might eat food sacrificed to idols and practice sexual immorality. 15 So also you have some who hold the teaching of the Nicolaitans.
Jesus hated that and still does.
