Unequally yoked

Notice how the chapter summary tells us to flee society and pollution of idolaters, that should include flee the worldly church as being ourselves temples of the living God.

CHAP. VI.
That hee hath approued himselfe a faithfull minister of Christ, both by his exhortations, 3 and by integritie of life, 4 and by patient enduring all kinds of affliction and disgraces for the Gospel. 10 Of which hee speaketh the more boldly amongst them, because his heart is open to them, 13 And he expecteth the like affection from them againe, 14 Exhorting to flee the societie and pollutions of Idolaters, as being themselues Temples of the liuing God.

(II Corinthians 6:14-18 [KJV])
 [14] Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness?
 [15] And what concord hath Christ with Belial? or what part hath he that believeth with an infidel?
 [16] And what agreement hath the temple of God with idols? for ye are the temple of the living God; as God hath said, I will dwell in them, and walk in them; and I will be their God, and they shall be my people.
 [17] Wherefore come out from among them, and be ye separate, saith the Lord, and touch not the unclean thing; and I will receive you,
 [18] And will be a Father unto you, and ye shall be my sons and daughters, saith the Lord Almighty.
