Spirituality: Charity from the Holy Spirit, G.C. 31, Decree 16

God, pouring forth his charity in our hearts through the Holy Spirit, confers upon some in the Church the gift of consecrated chastity, a sign of charity and likewise a stimulus to it, whereby they may more easily devote themselves with an undivided heart to him alone and to the service of his kingdom. Therefore, chastity "for the sake of the kingdom of heaven," to which by both his example and his calling Christ invites us, and which we as religious profess, following the lead of so many saints, should, as the Church repeatedly urges and as our founder expressly declares, be "perfectly observed" by us.
