Matthew, here are your own words from a previous thread:
i do not belong to a church that holds a confession. Actually i bet 95 % of my church doesnt know what a confession is.
I don't quote you to pick on you brother, but simply to show that, as wise brothers have noted, Grudem is NOT confessional. For so many champion & recommend his systematic, which isn't just non-confessional, but contra-confessional in several areas, is quite disappointing. So what if Grudem's style of writing is easy to read? You know who else is easy to read? 99% of the fluff on evangelical bookstores these days. Don't be lazy. Be willing to do the hard work and study solid, confessional writers. If you want to read a solid ST, read Berkhof. Read Bavinck. Read Beeke’s A Puritan Theology. If you need more recommendations, then search the archives on here or start a new thread.
As for the line of thinking that Grudem’s ST is the best recommendation for new converts due to it's "readability", I simply disagree. This isn't a case where we are on a deserted island with only a limited number of resources and so Grudem wins out. No, there are several easy-to-read sources that are better to give to new converts. First, the Westminster Standards themselves. Next, as Rom mentioned, Williamson and Vos' commentaries on the WCF and WLC. Next, someone mentioned that if Sproul had written a ST, they'd recommend that. Well, Sproul has written a three volume, lay-level commentary on the WCF, so why not recommend that? Again, if you are a confessional believer, which every member on this board is supposed to be, then there are numerous better options than Grudem’s contra-confessional ST.
