- 6th century AD, Angelramnus Metensis, Collectio Canonum Regulae Ancyrani concilii numero XXIV priores quidem sunt Nicaenis: sed ideo Nicaenis istae postponuntur, propter sancti et magni concilii auctoritatem Nicaeae congregati..XV:
  Nondum vicennes, post XV annos in poenitentia exactos, orationum communionem recipiant. Deinde post quinquennium communionem altaris percipiant. Quibus etiam prolixius tempus ad agendam poenitentiam imponendum est, si tale scelus frequentaverint. Qui autem jam vicennarii et uxorati ita peccaverint, XXVI annis poenitentia exactis tandem in oratione communicent, deinde post quinquennium oblationis sacramenta percipiant. Qui vero quinquagenarii et uxorati ita peccaverunt, tandem ad exitum vitae communionem recipiant.
