The surpassing worth of knowing Christ Jesus

Whoever is called "to teach Christ" must first seek "the surpassing worth of knowing Christ Jesus"; he must suffer "the loss of all things. . ." in order to "gain Christ and be found in him", and "to know him and the power of his resurrection, and [to] share his sufferings, becoming like him in his death, that if possible [he] may attain the resurrection from the dead".

—Catechism of the Catholic Church, paragraph 428
