Please read the passage before reading the commentary
This is a beautiful passage, often used at weddings to proclaim the love of bride and groom for each other. This passage does fit the occasion.
Consider, however, that this is not abstract advice given to a marrying couple. In the context of the whole letter to the Corinthians, it takes on added meaning. The things that love is not are the very things that Paul had found the Corinthians doing in their assemblies and in their interactions with one another. They had factions, followers of Apollos versus those of Paul. They had a caste system that put some people in higher tatus than others. They had people who preferred their own interests to the detriment of their neighbors. In many respects the Corinthians were childish in their behaviors, whereas they were called into the Church into grow to adulthood in Christ.
Now for those getting married, we are encouraging to give up the childish ways of former relationships and seek adultly the good of the other over the individual goods of self. They should not fashion the married life on the way the Corinthians were living what they called their “Christian life”.
The way of the Christian community, either in the house church of the married or in the broader community of parish, region or department, is to be the way of forgiveness, support, humility, unity and cooperation. It is the way of those who have taken to heart the teaching of Paul in the first twelve chapters of this letter and which he has summarized in this thirteenth chapter. This way of the Christian community is supposed to be our way as individual Christians and members of our local Christian gathering.
