William Burkitt on 1 Corinthians 16:14

Our apostle having in the beginning of this epistle reproved the Corinthians for their uncharitable schisms and unchristian divisions; he concludes his epistle with this excellent rule of advice, To do all things in love, one for and one towards another. Where a true principle of Christian charity prevails amongst the members of a church, it will cast out selfishness, pride, envy, division; and keep them from rash censuring, despising, and abusing one another, and also from separating from the communion of each other.

The sum of all the commandments, both towards God and towards our neighbour, is love; it is not praying, hearing, or receiving at the Lord's table, which is the fulfilling of the commandment, but when these duties are done in love; and we may do many things commanded towards men, yet if we do them not in love to men, we do nothing as the Lord commanded; therefore let all things be done with charity.
