Paul speaking to Timothy said, "O Timothy, keep that which is committed to thy trust, avoiding profane and vain babblings, and oppositions of science falsely so called:..." When does one determine that a thread has come to the level Paul instructed Timothy to avoid? Is it a certain type of thread; is it certain topics that should be avoided? Is it when a certain degree of useless discussion in which edification of any substance is no longer offered; is it in the temperament of hostility or intent to argue out of bully contentiousness. What would you state is the point when avoidance is actually good? Or is Paul stating that Timothy is to keep the truth of the Scriptures and not be involved with discussions that would undermine the intrusted principles Tim has built upon the foundation of faith reflecting what Paul stated in his letter to the Corinthians, "For other foundation can no man lay than that is laid, which is Jesus Christ. Now if any man build upon this foundation gold, silver, precious stones, wood, hay, stubble; Every man's work shall be made manifest: for the day shall declare it, because it shall be revealed by fire; and the fire shall try every man's work of what sort it is. If any man's work abide which he hath built thereupon, he shall receive a reward. If any man's work shall be burned, he shall suffer loss: but he himself shall be saved; yet so as by fire."
