Religion is Satan’s kingdom and yes, he has synagogues and he has worshipers (to render religious reverence to a deity).
That is why Jesus told them they were of their father the devil.
It most definitely is a heart condition because Satan has filled their heart and they worship him in his temples. Now not all synagogues are of Satan!! I am merely pointing out to you he does have some according to the scriptures.
Of course, these think they are serving God, but they are truly deceived, clearly we can see them in Jesus’s day and how they handled Jesus. If they had know who he was they would not have crucified the Lord of Glory.
“Behold, I will make them of the synagogue of Satan, which say they are Jews, and are not, but do lie; behold, I will make them to come and worship before thy feet, and to know that I have loved thee,”Revelations 3:9.
“I know thy works, and tribulation, and poverty, (but thou art rich) and I know the blasphemy of them which say they are Jews, and are not, but are the synagogue of Satan.” Revelation 2:9.
“I know thy works, and where thou dwellest, even where Satan’s seat is: and thou holdest fast my name, and hast not denied my faith, even in those days wherein Antipas was my faithful martyr, who was slain among you, where Satan dwelleth,”Revelation 2:13.
“These things have I spoken unto you, that ye should not be offended. They shall put you out of the synagogues: yea, the time cometh, that whosoever killeth you will think that he doeth God service. And these things will they do unto you, because they have not known the Father, nor me,”John 16:1-3.
