The Apostle Paul
Romans 15:1BSB·traditional attribution

We who are strong ought to bear with the shortcomings of the weak and not to please ourselves.

John Calvin Reformed @genevareformer

1. We then who are strong, etc. Lest they who had made more advances than others in the knowledge of God should think it unreasonable, that more burden was to be laid on them than on others, he shows for what purpose this strength, by which they excelled others, was bestowed on them, even that they might so sustain the weak as to prevent them to fall.

Matthew Henry Presbyterian @wholebiblehenry

The apostle here lays down two precepts, with reasons to enforce them, showing the duty of the strong Christian to consider and condescend to the weakest. I. We must bear the infirmities of the weak, Rom 15:1. We all have our infirmities; but the weak are more subject to them than others - the weak in knowledge or grace, the bruised reed and the smoking flax.

John Gill Reformed Baptist @doctorgill

Let everyone of us please his neighbour,.... Every man, particularly his Christian friend and brother, whom he should seek to please in all things, and by all means lawful; he should carry it affably and courteously, should make himself agreeable to him; should condescend and accommodate himself to his weakness, and bear his infirmities, and deny himself rather than displease him.
