One of my favorite WT articles is from 7/15 1985, pp. 10-14. That WT dealt with modern philosophies that tend to draw us away from God (Colossians 2:8). They are not necessarily theories, but rather philosophies of life. Cf. the German term Lebensphilosophie. Here is a brief quote from paragraph 16 of that article:
"Self-appointed judges and teachers pose yet another danger. Like those in Colossae, they may make issues of purely personal matters. They are often characterized by 'mock humility.' (Colossians 2:16-18) Their holier-than-thou attitude betrays a wrong motive—a desire to elevate themselves above others. They are often 'righteous overmuch,' quick to go beyond what the 'faithful slave' has said or published. Thus they may ignite controversies over such matters as recreation, health care, styles of dress and grooming, or the use of alcoholic beverages. (Ecclesiastes 7:16; Matthew 24:45-47) Attention is thereby diverted from spiritual matters and focused on fleshly desires."
I've just always liked this paragraph since it shows the rightful place of conscience in our worship to Jehovah. I have no intention of applying this material to anyone but myself.
All the best!
