A Sister of St. John the Baptist, through her religious congregation, makes solemn promises to God, called vows, to imitate Jesus by living certain Gospel values in a special manner:
Acknowledging that God is Love and that every human person is a channel of God’s love, through the vow of chastity the Sister chooses to express her love for others and her relationship with God through prayer and service to a wide circle of God’s family rather than by directing her love to one special person or human family.
Acknowledging that all life is dependent on God, through the vow of poverty the Sister strives to free herself from the excesses of material goods and consumption. Each Sister chooses to live a simple life and to share all goods in common, being mindful of each one’s obligation to the poor and to the stewardship of all of God's resources.
Acknowledging that the God's will is primary in her life, through the vow of obedience the Sister chooses to live in a community, to participate in its daily life, and to dedicate herself to furthering its goals, its hopes and its mission. To accomplish this the Sister commits herself to listening to and responding to the will of God as expressed by her fellow Sisters, her religious superiors and the signs of the times in society.
