Verse 1
Ch. 15:1-13 still following the theme of ch. 14 -
Reconciliation of Jewish Christians and Gentile Christians
We who are strong -- Paul aligns himself with those he identifies as strong in faith, and he reveals that the division in the Roman church was not simply between Jews and Gentiles. - NLTSB
strong...weak -- For modern English readers, to label the two perspectives “strong” and “weak” is to prejudice the groups. This was not Paul’s intent. The strong group referred to those who had been freed from a rule or ritual-oriented religious life. - Utley
to bear . . The word means “to pick up and carry a weight.” It is used of carrying a pitcher of water (Mark 14:13), of carrying a man (Acts 21:35), and figuratively of bearing an obligation (Acts 15:10). The strong are not to simply tolerate the weaknesses of their weaker brothers; they are to help the weak shoulder their burdens by showing loving and practical consideration for them (Galatians 6:2; cf. 1 Corinthians 9:19-22; Philippians 2:2-4). - MSB
the able -- The word rendered “able” is the same word as that rendered “mighty” in E. V. of e.g. Luke 24:19; Acts 18:24; 1 Corinthians 1:26; and “strong” in E. V. of 2 Corinthians 12:10. It seems to convey the thought of strength and something more; the resources and opportunities of strength. Able thus best represents it. Bp Lightfoot (on Philippians 2:15) suggests that it may have been a favourite title for themselves amongst the persons here contemplated; and so that there is irony in its use here. - CBSC
infirmities [scruples].. weaknesses.
the weak -- Lit. the unable; in contrast to “the able” just above. Same word as Acts 14:8, (E. V. “impotent.”)
The term “the weak” (adunates, without strength, cf. Romans 8:3) is different from the term astheneō in rom 14:1-2, rom 14.21 (cf. 1 Corinthians 8:7, 3x in 1 Corinthians 8:10-12; 1 Corinthians 9:22), which also means without strength. - Utley
The contrasting terms are δυνατός (dynatos, “able, empowered, possible, strong”) and ἀδύνατος (adynatos, “without power, unable, impossible, weak”). - CPNVC
and not just please ourselves ..” This is a PRESENT ACTIVE IMPERATIVE with the NEGATIVE PARTICLE, which usually means stop an act in process. Self-centeredness is a sure sign of immaturity; following Christ’s example (cf. v. 3; Philippians 2:1-11) is the sign of maturity. Again, it is the strong who were being addressed (cf. Romans 14:1, Romans 14:14, Romans 14:16, Romans 14:21-22). This is not to imply they had all the responsibility in maintaining the fellowship. The weak are addressed in Romans 14:3, Romans 14:20, Romans 14:23; Romans 15:5-6-7. - Utley
” This is a specific instance of the general principle in Gal 6:2, “Carry each other’s burdens.”
