For the second time in this letter Paul expresses concern that his labor in Galatia might be a total loss. He addresses the Galatians as brothers but seems freaked out about them observing "days, months, seasons and years". He seems to see this as a return to "weak and beggarly" basic principles which characterize the lost world and a return to slavery:
Gal 4:7 So you are no longer a slave, but a son, and if a son, then an heir through God. Gal 4:8 Formerly, when you did not know God, you were enslaved to those that by nature are not gods. Gal 4:9 But now that you have come to know God, or rather to be known by God, how can you turn back again to the weak and worthless elementary principles of the world, whose slaves you want to be once more? Gal 4:10 You observe days and months and seasons and years! Gal 4:11 I am afraid I may have labored over you in vain.
"OSAS" ("once saved, always saved") teaches that one can forfeit temporal benefits and rewards but never can lose one's ultimate justification. Does Paul suggest in this passage that the Galatian brothers might lose their ultimate justification? Or is he only concerned that they might forfeit temporal benefits and rewards?
The phrase "I may have labored over you in vain" seems to me to suggest that he was concerned his work among them would have no lasting effect but he doesn't seem to make that explicit.
Does this passage allow for a "temp and rewards only" loss? Or does it warn against actual apostasy and loss of ultimate justification?
Does the passage leave any room for the idea that if they returned to Torah that they never were regenerate to begin with?
