All gobbly gook that only proves 'something' - look at me.
While Paul put his life behind pointing to JESUS/TheTruth!
As usual, Daniel, great work!
McGrath's work is refuting the RC straw man of sola ecclesia as meaning the faith that appropriates justification need not be the kind of faith that will effect works, though the sinner comes to Christ as damned + destitute of any merit that would justify him as worthy of eternal life, but whose faith is counted for righteousness, and whose subsequent works testify to having a genuine, worthy faith.
The "easy believism" of some modern preaching is an aberration, while the Roman form of this is what it predominately effectually conveys today, which is basically that no matter how "nominal," you are a member of the RCC, and as long as you die in her hands she will get you into heaven. Thus you have the TRC sect within Rome in protest to this, but which contends for the gospel which overall fosters faith in the church for salvation, not Scriptural regeneration on personal repentant faith directly in the Lord Jesus.
