This term refers to the practice of advertising one's religiousity by wearing significant decolletage and having a cross suspended between the breasts. This is especially effective if the practitioner has either very prominent breasts or is not wearing a bra.
Jessica, who was both very religious and had been embarassed by her rather prominent breasts, made them into a spiritual asset by practicing decolletage ministry. She found it more effective than the John 3:16 signs.
