Since there are only two different powers in this world--either good or evil, and only two different sources of doctrine -- either light or darkness, so God's word lists only two kinds of churches--the pure righteous church of God (see Revelation 12:1-5; Ephesians 5:27), or the corrupt Babylonian synagogue of Satan (see Revelation 2:9, 17:1-6).
Yamang mayroon lamang dalawang magkaibang kapangyarihan sa sanlibutang ito maging mabuti o masama, at dalawa lamang magkaibang pinagmumulan ng doktrina maging liwanag o kadiliman, kaya't dalawang uri lamang ng iglesya ang nakatala sa salita ng Dios - ang dalisay at matuwid na iglesya ng Dios (tingnan ang Apokalipsis 12:1-5; Efeso 5:27), o ang bulok at Babiloniang sinagoga ni Satanas (tingnan ang Apokalipsis 2:9, 17:1-6).
