14:1 doubtful disputations. “Doubtful disputations” refer to critical judgments on the inward reasonings of others. Unless some practice is specifically revealed in Scripture to be right or wrong, each believer should be free to formulate his own convictions about it. New Christians may still feel constrained by certain criteria they had followed earlier, and thus may be reluctant to change when they become saved. Unless these are specifically enjoined or prohibited in the Word of God, older believers should receive them into fellowship without argument or criticism.
