Romans 14:22

Here he seems to me to be giving a gentle warning to the more advanced on the score of vanity. And what he says is this, Dost thou wish to show me that thou art perfect, and fully furnished? Do not show it to me, but let thy conscience suffice. And by faith, he here means that concerned not with doctrines, but with the subject in hand. For of the former it says, "With the mouth confession is made unto salvation" (Rom. x. 10); and, "Whosoever shall deny Me before men, him will I also deny." (Luke ix. 26.) For the former by not being confessed, ruins us; and so does this by being confessed unseasonably. "Happy is he that condemneth not himself in the thing which he alloweth." Again he strikes at the weaker one, and gives him (i.e. the stronger) a sufficient crown, in that of his conscience. Even if no man see, that is, thou art able to be happy in thyself. For after saying, "Have it to thyself," to prevent his thinking this a contemptible tribunal, he tells him this is better to thee than the world. And if all accuse thee, and thou condemn not thyself, and thy conscience lay no charge against thee, thou art happy. But this is a statement he did not make to apply to any person whatever. For there are many that condemn not themselves, and yet are great transgressors: and these are the most miserable of men. But he still keeps to the subject in hand.
