St. Paul's letters to the Corinthian church are written to a church torn by political and theological battles, a church unsure of its foundations and faith, a church struggling with issues of sexual morality and social pressure. So he reminds them:

Now I would remind you, brothers and sisters, in what terms I preached the Gospel, which you received and in which you stand. For I delivered to you as of first importance what I also received: That Christ died for our sins according to the scriptures, that he was buried and that he was raised on the third day, in accordance to the scriptures. (I Corinthians 15:1)

It's the reminder of the central message of the Gospel, a reminder of the word we have to proclaim. And today, just as in the Corinthian church, there is a desperate need for disciples of Christ to be grounded in the faith, to grow together in our spiritual journey, to nurture one another in the life and spirit of Jesus Christ.
