Grace (in salvation). (Gal 1:6); (Gal 1:15); (Gal 2:21); (Rom 3:24).
(See Scofield) - (Joh 1:17).
(See Scofield) - (Rom 3:23).
The test of the Gospel is grace. If the message excludes grace, or mingles law with grace as the means of either of justification or sanctification, (Gal 2:21); (Gal 3:1-3), or denies the fact or guilt of sin which alone gives grace its occasion and opportunity, it is "another" gospel, and the preacher of it is under the anathema of God. (Gal 1:8); (Gal 1:9).
For now do
The demonstration is as follows:
(1) The Galatians know Paul, that he is no seeker after popularity. (Gal 1:10).
(2) He puts his known character back of the assertion that his Gospel of grace was a revelation from God. (Gal 1:11); (Gal 1:12).
(3) As for the Judaizers, Paul had been a foremost Jew, and had forsaken Judaism for something better. (Gal 1:13-14).
(4) He had preached grace years before he saw any of the other apostles. (Gal 1:15-24).
(5) When he did meet the other apostles they had nothing to add to his revelations. (Gal 2:1-6).
(6) The other apostles fully recognized Paul's apostleship. (Gal 2:7-10).
(7) If the legalizers pleaded Peter's authority, the answer was that he himself had claimed none when rebuked. (Gal 2:11-14).
The new dispensation of grace having come in, the Mosaic system, if still persisted in, becomes a mere "Jews' religion."
In verses 13 and 14 (Gal 1:13-14), the Greek word for "the Jews' religion" is "Ioudaismos", (meaning "Judaism"). In (Act 26:5); (Jam 1:26); (Jam 1:27), the Greek word "threskeia" -- "religious service" -- is translated as "religion," and in (Col 2:18); it is translated as "worshipping." Excepting (Jam 1:27); "religion" has always a bad sense, and nowhere is it synonymous with salvation or spirituality.
