Where did you get that idea?
Ronnie the Rocket’s post 4, about a period of continence being required, is not receiving the attention that it deserves. Up until the time of St. Pius X, ALL OF THE FAITHFUL in the Latin Rite were expected to abstain from marital relations for three days prior to receiving Holy Communion—the rational may be found described in the Catechism of the Council of Trent under the section on the Eucharist, subsection titled Recipient of the Eucharist, sub-subsection titled Preparation of the Body (if you have the TAN edition, bottom of p. 248). Short version: abstain from food from midnight, abstain from food for three days.
This would preclude daily Mass if one had married priests exercising marriage. It also would require a great deal of mutually agreed to abstinence if at least one party in a marriage wanted to be a very frequent communicant.
While St. Pius X did away with the requirement of a sexual fast for the Latin Rite, he did not alter Canon Law on the matter of clerics, and if canon lawyer Edward Peters is right (and I am persuaded that he is), Canon Law has not been altered on the point. Misunderstood and misinterpreted, but not altered. http://www.canonlaw.info/a_deacons.htm
Peters’ position is detailed, and contains nuances regarding those ordained without knowledge of the law. As I need sleep, I will let him make the case in a way more precise and nuanced than I am capable of.
