Reasons Why a Christian Should Not be a Freemason [EPUB ebook] 

A Christian should not be a Freemason, for the Scripture command to him is, ‘Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness? and what concord hath Christ with Belial? or what part hath he that believeth with an infidel?’ (2 Cor. 6:14, 15). This is a command that all Christians are bound to obey, if they are to be consistent with their Christian profession. The contrast in this verse is sharp and well-defined. Can it be sustained in our present inquiry? ‘What fellowship hath Christ with Belial?’
In answer, let us quote Mr. J. S. M. Ward, Secretary-General of The Masonic Study Circle. He has written a number of text-books for the use of candidates preparing for the different degrees in the Masonic body. The introduction to these handbooks is written by Sir John Cockburn, Past Grand Deacon (of England), Past Deputy Grand Master (of South Australia). Surely these are credentials enough to show that he is an authority in Masonic circles, and that what he puts forth is their accepted belief.
