3:14. These things I write to thee, hoping that I shall come to thee shortly.

3:15. But if I tarry long, that thou mayest know how thou oughtest to behave thyself in the house of God, which is the church of the living God, the pillar and ground of the truth.

The pillar and ground of the truth…. Therefore the church of the living God can never uphold error, nor bring in corruptions, superstition, or idolatry.

3:16. And evidently great is the mystery of godliness, which was manifested in the flesh, was justified in the spirit, appeared unto angels, hath been preached unto the Gentiles, is believed in the world, is taken up in glory.

1 Timothy Chapter 4

He warns him against heretics, and exhorts him to the exercise of piety.

4:1. Now the Spirit manifestly saith that in the last times some shall depart from the faith, giving heed to spirits of error and doctrines of devils,

4:2. Speaking lies in hypocrisy and having their conscience seared,

4:3. Forbidding to marry, to abstain from meats, which God hath created to be received with thanksgiving by the faithful and by them that have known the truth.

Forbidding to marry, to abstain from meats…. He speaks of the Gnostics, the Marcionites, the Eneratites, the Manicheans, and other ancient heretics, who absolutely condemned marriage, and the use of all kind of meat; because they pretended that all flesh was from an evil principle. Whereas the church of God, so far from condemning marriage, holds it a holy sacrament; and forbids it to none but such as by vow have chosen the better part: and prohibits not the use of any meats whatsoever in proper times and seasons; though she does not judge all kind of diet proper for days of fasting and penance.
