Revelation 2:2-5

I know your works, and your hardship and patient endurance, and that you cannot stand those who are evil. And so, you have tested those who declare themselves to be Apostles and are not, and you have found them to be liars. And you have patient endurance for the sake of my name, and you have not fallen away. But I have this against you: that you have relinquished your first charity. And so, call to mind the place from which you have fallen, and do penance, and do the first works. Otherwise, I will come to you and remove your lampstand from its place, unless you repent.
