Westminster is committed to Scripture and to the Reformed faith, and so are our professors. In fact, every voting member of the faculty takes the same pledge when they are hired:
"I do solemnly declare, in the presence of God and of the Trustees and Faculty of this Seminary, that (1) I believe the Scriptures of the Old and New Testaments to be the Word of God, the only infallible rule of faith and practice; and (2) I do solemnly and ex animo adopt, receive, and subscribe to the Westminster Confession of Faith and Catechisms in the form in which they were adopted by this Seminary in the year of our Lord 1936, as the confession of my faith, or as a summary and just exhibition of that system of doctrine and religious belief, which is contained in Holy Scripture, and therein revealed by God to man for his salvation; and I do solemnly, ex animo, profess to receive the fundamental principles of the Presbyterian form of church government, as agreeable to the inspired oracles. And I do solemnly promise and engage not to inculcate, teach, or insinuate anything which shall appear to me to contradict or contravene, either directly or impliedly, any element in that system of doctrine, nor to oppose any of the fundamental principles of that form of church government, while I continue a member of the Faculty in this Seminary. I do further solemnly declare that, being convinced of my sin and misery and of my inability to rescue myself from my lost condition, not only have I assented to the truth of the promises of the Gospel, but also I have received and rest upon Christ and His righteousness for pardon of my sin and for my acceptance as righteous in the sight of God and I do further promise that if at anytime I find myself out of accord with any of the fundamentals of this system of doctrine, I will on my own initiative, make known to the Faculty of this institution and, where applicable, my judicatory, the change which has taken place in my views since the assumption of the vow."
