On Observing Lent

Apostolic Canons ca. 1st cent.

If any bishop, presbyter, or deacon, or reader, or singer, does not fast the holy Quadragesimal fast of Easter, or the fourth day, or the day of Preparation, let him be deposed, unless he be hindered by some bodily infirmity. If he be a layman, let him be excommunicated. (Canon 69)
