Albert Barnes Commentary Romans 15:2

"Let each one of us please his neighbor for that which is good, unto edifying." — Romans 15:2 (ASV)

Please his neighbour. That is, all other persons, but especially the friends of the Redeemer. The word neighbour here has special reference to the members of the church. It is often used, however, in a much larger sense. See Luke 10:36.

For his good. Not to seek to secure for him indulgence in those things which would be injurious to him, but in all those things by which his welfare would be promoted.

To edification. See the notes on Romans 14:19.
