Analysis of information sources in references of the Wikipedia article "Nước thánh" in Vietnamese language version.
Holy water has no power to beautify the soul here in time and the body in eternity, as Penance and the Eucharist have; but for those who reverently use it, having the right dispositions of faith and contrition, it has power to banish demons, dispel their deceits and vexations, cleanse the soul from stain of venial sins, avert earthly ills (other than those which God allows for our good), and to promote our temporal welfare.
