When Wiersbe wrote "the church" did he mean "the church"?
It made no sense in the context of Galatians 2 that "some teaching salvation by ritual, others insisting on mixing law and grace" would be consider "church"
Wiersbe’s Expository Outlines on the New Testament
The church today is still divided, with some teaching salvation by ritual; others insisting on mixing law and grace. The minority hold to Paul’s Gospel of the grace of God.
- I think that perhaps Wiersbe is referring to the "visible church" as in this article: Theologians sometimes distinguish between the “visible church” (the church as Christians on earth see it) and the “invisible church” (the church as God in heaven sees it). This distinction emphasizes two truths. First, only God, who reads hearts, knows the ultimate makeup of the “invisible church”—those whom he has called (“The Lord knows those who are his,” 2 Tim. 2:19). Second, there are some within the “visible church” who are not genuine believers, though they may look as if they are (cf. Matt. 7:15–16; Acts 20:29–30; 1 John 2:19). Crossway Bibles. (2008). The ESV Study Bible (p. 2532). Wheaton, IL: Crossway Bibles. I think sometimes genuine believers can fall into error regarding doctrine, but they can be corrected. I think to insist on teaching something that amounts to a false gospel puts one outside the category of a genuine believer, and not part of the invisible church. What do you think?
