FIRST COUNCIL OF NICAEA - 325 AD - CANONS
*11. Concerning those who have transgressed without necessity or the confiscation of their property or without danger or anything of this nature, as happened under the tyranny of Licinius, this holy synod decrees that, though they do not deserve leniency, nevertheless they should be treated mercifully. Those therefore among the faithful who genuinely repent shall spend three years among the hearers, for seven years they shall be prostrators, and for two years they shall take part with the people in the prayers, though not in the offering.
Those who have been called by grace, have given evidence of first fervour and have cast off their [military] belts, and afterwards have run back like dogs to their own vomit, so that some have even paid money and recovered their military status by bribes – such persons shall spend ten years as prostrators after a period of three years as hearers.
Since there are some who kneel on Sunday and during the season of Pentecost, this holy synod decrees that, so that the same observances may be maintained in every diocese, one should offer one’s prayers to the Lord standing.*
As the Eastern Churches all still do, the Early Church generally stood on Sunday (symbolyzed being resurrected together with Christ) and knelt on the rest of the days of the week (partly to differentiate them from Sunday).
The Early Church EAGERLY awaited our Lord’s Coming “from the East”, so the entire congregation faced the East in the hopes of being the first to see Our Lord coming in the clouds.
