Eliza R. Snow writes in EXPONENT, and LDS women's journal, of women blessing one another through laying on of hands and washing and anointing: "Any and all sisters who honor their holy endowments, not only have the right, but should feel it a duty, whenever called upon to administer to our sisters in these ordinances, which God had graciously committed to His daughters as well as to His sons; and we testify that when administered and received in faith and humility they are accompanied with all mighty power. . . . thousands can testify that God has sanctioned the administration of these ordinances [of healing the sick] by our sisters with the manifestation of His healing influence."
