Peter erred in life and in doctrine. Paul might have dismissed Peter's error as a matter of no consequence. But Paul saw that Peter's error would lead to the damage of the whole Church unless it were corrected. Therefore he withstood Peter to his face. The Church, Peter, the apostles, angels from heaven, are not to be heard unless they teach the genuine Word of God.

Against the flying ball no valor avails.

If ever the church is to flourish again, one must begin by instructing the young.

No man should be alone when he opposes Satan. The Church and the ministry of the Word were instituted for this purpose, that hands may be joined together and one may help another.

For all works and things, which are either commanded or forbidden by God and thus have been instituted by the supreme Majesty, are 'musts.' Nevertheless, no one should be dragged to them or away from them by the hair, for I can drive no man to heaven or beat him into it with a club.

Sin is essentially a departure from God.

Our loving God wills that we eat, drink and be merry.
