From Richard Baxter’s A Christian Directory Chapter 2, Part 1, page 40,

“Begin not too early with controversies in religion: and when you come to them, let them have but their due proportion of your time and zeal: but live daily upon these certain great substantials, which all christians are agreed in.
Plunge not yourselves too soon into controversies: For, (1) It will be exceedingly your loss, by diverting your souls from greater and more necessary things: you may get more increase of holiness, and spend your time more pleasingly to God, by drinking in deeper the substantials of religion, and improving them on your hearts and lives.
(2) It will corrupt your minds, and instead of humility charity, holiness, and heavenly-mindedness, it will feed your pride, and kindle faction and a dividing zeal, and quench your charity, and possess you with a wrangling, contentious spirit, and you will make a religion of these sins and lamentable distempers.”
