Wayne Grudem's Systematic Theology text

It depends on what you mean by Reformed. My standard for Reformed theology is the Westminster Standards and the other Reformed confessions. So, by that standard, Grudem deviates from Reformed theology at several points. But, if you’re restricting your question simply to soteriology, then Grudem is pretty close.

I do have one dissatisfaction with his treatment of the ordo salutis. I think he misses the emphasis on union with Christ. In Reformed theology, believers get one central benefit - union with Christ. Now, Christ’s union with the believer results in a twofold grace (duplex gratia), justification and sanctification. (Later Reformed theology would add a third, adoption, previously treated with justification.) In conjunction with this, I (along with Calvin and the Scottish Marrow theologians) prefer to see a slight priority of faith over repentance, whereas Grudem makes them pretty much dead even.

For more information along this line, see the appropriate section in Sinclair Ferguson’s The Holy Spirit or consult Richard Gaffin’s By Faith, Not By Sight. There’s a brief treatment by Michael Horton available in the link below, but the chapters on union with Christ in his new The Christian Faith is definitely worth a read. For a very thorough but readable work, I recommend Accepted and Renewed in Christ: The “Twofold Grace of God” and the Interpretation of Calvin’s Theology by Cornelis Venema.
