WTS is an interesting place. How the last controversy was handled was done very poorly. All of this is public information and not at all gossip, and ought to to be said in order to inform anyone who thinks of going to WTS what it is like and what it supports. Dr. Duguid can correct me where I am wrong.
The Recent Background Controversy
The most recent controversy was over Dr. Oliphint and his "God With Us" book and apparent revision. The book is a hilarious $165 on Amazon now, because most of the books were burned. The controversy was over "Theological Mutualism" as I've heard it called, which is basically attempting to answer how God relates to the world. Dr. Oliphint's solution was to say that God has "Covenantal Properties," and that in God's Covenantal face, he actually does change: so when God called out "where are you" to Adam and Eve, it was a real question of where they were, not rhetorical. In the end, the question is - when God and man relate, is there necessarily a change in God (that would collapse the creator-creature distinction)? Ultimately, the answer must be no, because of the aseity of God - God cannot be determined by anything outside of himself, let alone by creation. But Oliphint thinks the answer is yes, that God must make a change in himself in order to relate to creation.
Dr. Oliphint was brought up on charges and tried in the OPC Presbytery of the Southwest, but eventually it stalled (if I remember correctly) on the statute of limitations, because the book was published beyond the statute. Dr. Oliphint has never recanted his views, but he has said he will not speak on them anymore, something I can't confirm that he has done or not, as he has continued to teach Apologetics and Doctrine of God at WTS, although he just recently announced his retirement.
The Lingering Effects
The point I have in relating all of this background - through all of this, Dr. Tipton, left or was fired in relation to this. That is, the seminary's official statement was intentionally vague with Dr. Tipton's case, and made it seem like Dr. Tipton was let go for a sin issue - when he simply vehemently disagreed with Dr. Oliphint. Since then, Dr. Beale, Dr. VanDixhoorn, and Dr. Briones have also left - whether in connection to these things or not, I don't know, but I suspect they have. Again, all of this is public information.
I have a hard time believing that the Confessionalists won in this case, as many of those who... left, were deeply confessional. I have great respect for many of the professors who are still at WTS, as many - like Dr. Duguid - are also confessional, and so I have hope for WTS, but I left WTS deeply disturbed, even if I left with an MDiv. I simply no longer trust the administration after all the maneuvering. This is unpresbyterian, as one of the great things of Presbyterians is that we "have it out" on the floor, so to speak, and embrace one another as brothers afterwards, all to the glory of God. This never happened when people "left."
However, Financially and Strategically, the seminary is demolishing Van Til Hall - an old utilitarian building - to build a new hall with eventual dorms. They have been working on having a dedicated, payed for, in person MDiv program for years - and finally succeeded. Machen had this as his vision for the seminary even during the great depression. These are exciting things in the abstract, but I honestly worry - and this is conjecture - that the seminary has followed these dreams too closely with neglect to orthodoxy, and have become a seminary based upon strategic goals and not upon God's glory alone. Their relationship with the OPC now feels much stranger and indeterminate, if I may voice my feelings and the feelings I know from other OPC voices I respect.
I believe the Theological Mutualism which Oliphint has taught in the past is heresy akin to Open Theism. Regardless of what I believe, do not go into WTS wishy washy on Theological Mutualism (or, Correlativism).
You have my
