In short, when persons have once taken upon them to tyrannize over men’s souls, there is no end of new laws being daily added to old ones, and now enactments starting up from time to time. How bright a mirror there is as to this in Popery! Hence Paul acts admirably well in admonishing us that human traditions are a labyrinth, in which consciences are more and more entangled; nay more, are snares, which from the beginning bind in such a way that in course of time they strangle in the end.

Those who add commandments, are trying to come up with some obediences they think they CAN handle!
To give up trying to establish their own righteousness before God, like the Jews of Paul’s day, they refuse to do.
