Revelation 2:15

So hast thou also them that hold the doctrine of the
Nicolaitans
These impure heretics sprung up in the time of the apostolic church, but their doctrines were not received, and their deeds were hated, see ( Revelation 2:6 ) . This seems to design the doctrines of the church of Rome, which in this period took place; which forbid marriage to the priests, and recommended celibacy and virginity to others also; which were the source of all uncleanness and abominable lusts; for which pardons and indulgences were given, and, in process of time, brothel houses were set up, and licensed and encouraged by authority.

Which thing I hate;
the doctrine of these men, as well as their deeds.
