Under the liturgical laws pertaining to the Extraordinary Form, the Faithful may not receive the Precious Blood, but only the Host, by contrast with the widespread practice, at least in Europe and North America, in the Ordinary Form. Historically, the Faithful received the Precious Blood in the West through a tube or fistula, until this died out in about the 12th century, with certain exceptions. Sacrosanctum Concilium proposed a revival of a practice exceptional reception of the Precious Blood, although permission soon became more general. The practice of the Extraordinary Form has certain advantages. It underlines the sacrificial nature of the Mass, for which the Priest’s reception from the Chalice is ritually necessary, but the Faithful’s is not. It safeguards the respect for the Sacred Vessels characteristics of the Extraordinary Form, which is incompatible with the usual practice of the Ordinary Form. It avoids a number of practical difficulties and liturgical abuses which have sometimes arisen in the Ordinary Form. And it guards against certain dangers to public health.
