Theology was designed for institutions of learning, not for ordinary Christians. It originated from the Scholasticism of the Catholic church, but continued with the Protestants, and then with the Evangelicals. Gradually it became almost automatic for pastors to go to seminaries (just as priests were required to attend seminaries) in order to be "academically qualified" to preach.
The issue of "gifts and calling" was more or less set aside. But that is not how the New Testament pattern was set up. Jesus and the apostles avoided the rabbinic schools altogether (even Paul set aside his theological background after his conversion, being taught directly by Christ). Churches were to have elders who would teach faithful men sound Bible doctrine, with the Holy Spirit as the divine Teacher. But all that changed shortly after the passing of the apostles.
However it became the standard operating procedure for churches to have pastors attend seminaries and receive academic degrees. Today most churches want their pastors to have a Master of Theology degree (at the very least) to even be considered for a "job". Theology does lock in its adherents to systems of interpretation used by their denominations. For example, Wayne Grudem's theology is Calvinistic, so those reading his book will be influenced in that direction (which is a false gospel). Many other theologians were also of the Reformed persuasion in the past.
So people need to study theologies keeping in mind that some ideas could be misleading. For example, Amillennialism is the standard eschatology of some denominations. So they will oppose any other interpretations.

Wayne Grudem is also a continuationist which is not the norm for a reformist. It is an example of intellectual honesty. He is trying his best to interpret scriptures correctly.
I think that is why I like Wayne Grudem. He is intellectually honest and I love that in a brother. He is not perfect, and none of us have it all perfectly figured out yet, but I can tell that he is laser focused on discovering authorial intent as much as possible.
I have not read enough of F.F. Bruce to be sure, but I have a good feeling about his intellectual honesty as well. Writers who are willing to concede to an interpretation that is not what their denomination teaches is always a good sign of intellectual honesty. They risk being defrocked by their denomination by interpreting a verse differently because they only want to interpret it correctly and are not moved by fear of man or repercussions from their denomination. Gordon Fee is another one I highly respect. He departs from the position of the denomination that ordained him because he is focused on correct interpretation.
