8 We begin the fast of forty days on the 13th of the month Phamenoth. After we have given ourselves to fasting in continued succession, let us begin the holy Paschal week on the 18th of the month Pharmuthi (April 13). Then resting on the 23rd of the same month Pharmuthi (April 18), and keeping the feast afterwards on the first of the week, on the 24th (April 19), let us add to these the seven weeks of the great Pentecost, wholly rejoicing and exulting in Christ Jesus our Lord, through Whom to the Father be glory and dominion in the Holy Ghost, for ever and ever. Amen.
The brethren which are with me salute you. Salute one another with a holy kiss.
Here ends the second Festal Letter of the holy lord Athanasius, Bishop of Alexandria.
