Richard Baxter on Hot Orthodoxy

Your first question must be, Whether you are in the right way? and your second, Whether you go apace? It is sad to observe what odious actions are committed in all ages of the world, by the instigation of misguided zeal! And what a shame an imprudent zealot is to his profession! While making himself ridiculous in the eyes of the adversaries, he brings his profession itself into contempt, and maketh the ungodly think that the religious are but a company of transported brain-sick zealouts; and thus they are hardened in their perdition. How many things doth unadvised affection provoke well-meaning people to, that afterwards will be their shame and sorrow.

Labour therefore for knowledge, and soundness of understanding; that you may know truth from falsehood, good from evil; and may walk confidently, while you walk safely; and that you become not a shame to your profession, by a furious persecution of that which you must afterwards confess to be an error; by drawing others to that which you would after wish that you had never known yourselves. And yet see that all your knowledge have its efficacy upon your heart and life; and take every truth as an instrument of God, to reveal himself to you, or to draw your heart to him, and conform you to his holy will. A Christian Directory, Part I, Chapter II, Direct. II.
