I can't speak for other religions.... but:
Christ is the center of all Christian life. The bond with him takes precedence over all other bonds, familial or social. From the very beginning of the Church there have been men and women who have renounced the great good of marriage to follow the Lamb wherever he goes, to be intent on the things of the Lord, to seek to please him, and to go out to meet the Bridegroom who is coming. Christ himself has invited certain persons to follow him in this way of life, of which he remains the model.
