In his message to the Church in Pergamum, Christ takes to task a church that was trying to stay true to the fundamentals of the faith while compromising on the practice of morality. It appears, according to Christ, true, obedient Christianity is not maintaining historic, biblical Christology while softening stands on sexuality and idolatry. This seems to me a letter rife with application to the church today. I think we, in the Western world in particular, need to see the line Christ drew regarding these "tangentials"--there is a lot at risk!
It is possible for one to say the right things about who Christ is and what he has done, even to the point of martyrdom, but if one is soft on sexual license or the fixations and substitutions which are idolatry, that one has failed Christ. What a bracing thought! The cost of such failure is being being treated as an enemy of Christ, at war with him and subject to the judgment of his word. The benefit of repentance and success is being treated to a special intimacy with Christ, something shared with Christ that is the victors' alone.
That should be an easy choice, but never undersell the flesh's power to cloud our moral vision, even when the risk is huge!
