The vow of chastity is undertaken for the sake of the kingdom of heaven.
By chastity, the heart is capable of even greater love of God, is more available in the service of others.
As well, it can be dedicated to the undivided service of Christ and his church in all forms of the apostolate.
In that we all are vessels of clay, the preservation of the treasure of chastity must always rely on the help of God.
Augustine explained that the dignity and worth of chastity does not consist in continence (a voluntary restriction of sexual matters) as such, but in its being offered to God as a holy gift.
In addition, chastity is linked to the community existence that religious share, and is supported and safeguarded in a community where true love and mutual vigilance exists among the members.
Accordingly the Rule
of Augustine states, "Exercise a mutual care over purity of life. Thus, by mutual vigilance over one another, will God, who dwells in you, grant you his protection."
