Romans 14:5

(6) One man esteemeth one day above another: another esteemeth every day [alike]. (7) Let (d) every man be fully persuaded in his own mind.

(6) Another example of the difference of days according to the law. (7) He sets against this contempt, and hasty or rash judgments, a continual desire to profit, that the strong may be certainly persuaded of their liberty, of what manner and sort it is, and how they ought to use it: and again the weak may profit daily, in order that they do not abuse the gift of God, or please themselves in their infirmity.

(d) That he may say in his conscience that he knows and is persuaded by Jesus Christ, that nothing is unclean of itself: and this persuasion must be grounded upon the word of God.
