'Opinions' in the Bible

Brothers, in the name of our Lord Jesus the Messiah, I urge all of you to be in agreement and not to have divisions among you, so that you may be perfectly united in your understanding and opinions.

just as I please everyone in all things [as much as possible adapting myself to the interests of others], not seeking my own benefit but that of the many, so that they [will be open to the message of salvation and] may be saved.
