Bluntly, we need to consider them as containing Christians. I was once ready to say that "Anglicans" and "Methodists" are like this and that, but there are many deeply believing Methodists and Anglicans still in these churches.
I think we need to believe that there are some still remaining
Mad Dawg brought his deep thoughts and prayerfulness to us from the Anglican Church and he related a story some time ago that he as a member of the clergy there protested against a strong transgression by the Anglican Church. He got no response and that's when he moved stock-lock-and two smoking barrels.
So, I do believe that there are still good people left, but their numbers are diminishing, sadly
I have no problem with that, as every Church has a remnant in it if it was ever alive in the first place. I'm starting to really wonder if the teaching about the Seven Churches mentioned in Revelation being the Seven Church Ages may be correct. This seems very similar to what Christ said to the Church of Thyatira.
[18] And unto the angel of the church in Thyatira write; These things saith the Son of God, who hath his eyes like unto a flame of fire, and his feet [are] like fine brass; [19] I know thy works, and charity, and service, and faith, and thy patience, and thy works; and the last [to be] more than the first. [20] Notwithstanding I have a few things against thee, because thou sufferest that woman Jezebel, which calleth herself a prophetess, to teach and to seduce my servants to commit fornication, and to eat things sacrificed unto idols. [21] And I gave her space to repent of her fornication; and she repented not. [22] Behold, I will cast her into a bed, and them that commit adultery with her into great tribulation, except they repent of their deeds. [23] And I will kill her children with death; and all the churches shall know that I am he which searcheth the reins and hearts: and I will give unto every one of you according to your works. [24] But unto you I say, and unto the rest in Thyatira, as many as have not this doctrine, and which have not known the depths of Satan, as they speak; I will put upon you none other burden. [25] But that which ye have [already] hold fast till I come. [26] And he that overcometh, and keepeth my works unto the end, to him will I give power over the nations: [27] And he shall rule them with a rod of iron; as the vessels of a potter shall they be broken to shivers: even as I received of my Father. [28] And I will give him the morning star. [29] He that hath an ear, let him hear what the Spirit saith unto the churches. - Rev 2:18-29 KJV
