The most ancient Christian writers unanimously testify that the Holy Forty Day Fast was established by the apostles in imitation of the forty-day fast of Moses (Exodus 34), Elijah (3 Kings 19), and mainly by the example of Jesus Christ fasting for forty days (Mat. 4:2). Ancient Christians have observed the time of the Holy Forty Days as the season of the commemoration of the Suffering of the Savior on the Cross, anticipating the days of this commemoration, so that, strongly imitating His self-renunciation and His self-denial, these ascetical feats would show the living participation and love on the part of the Savior, who suffers for the world, and that before all this to be morally cleansed for the time of the solemn commemoration of the passion of Christ and His glorious resurrection. The very name of the Holy Forty Days is met rather frequently in the most ancient written monuments with the indication of the purpose of its establishment. "Do not neglect the Forty Days", wrote St. Ignatius the God-bearer in his epistle to Philippians: "for it establishes the imitation of the life in Christ". St. Ambrose of Milan spoke even more clearly: "The Lord has blessed us with the Forty Day Fast. He created it for our salvation to teach us to fast not in words only, but also by example". Ss. Basil the Great and Gregory of Nyssa assert that the Holy Forty Day Fast existed everywhere during their time. According to the Apostolic Canons (Canon 69) the Holy Forty Day Fast is considered obligatory and its observance is protected by strict punishment. St. Hippolytus (3 century) serves as the indisputable witness of the antiquity of this fast and the paschal cycle traced to his See, containing the instruction from antiquity of the custom to stop the Holy Forty Days Fast on Sundays. On the basis of all traditions of the Holy Apostles, our Holy Church, through her holy fathers and teachers, always considered the Holy Forty Day Fast an apostolic establishment. As the Blessed Jerome, on behalf of all Christians of his time said: “we fast for the Forty Days according to the apostolic tradition.” St. Cyril of Alexandria repeatedly reminds us in his writings, that it is necessary to piously observe the Holy Forty Day Fast, according to the apostolic and gospel traditions…

"The more days of the fast", teaches the blessed Augustine, "the better the healing. The longer the abstention, the more bountiful is the salvation. God, the Physician of our souls, established the proper time for the pious to give praise, for the sinners to pray; for some to seek rest, for others to ask forgiveness. The time of the Holy Forty Days is proper, neither too short for giving praise, nor too long for seeking mercy. Holy and saving is the course of the Holy Forty Days by which the sinner is led through repentance to charity, and through piety to rest. During its days God is supremely propitious, needs are met, piety is rewarded".

"The holy fathers", teaches St. John Chrysostom, "appointed forty days of fast in order that during these days the people, having been carefully cleansed through prayer, fasting and confession of sins, will approach Holy Communion with a pure conscience ".

According to the teaching of the Venerable Dorotheos of Gaza, "God has given these holy days (the Forty Holy Days) so that those who struggle, with attention and wise humility, who tend to themselves and repent, will be cleansed of the sins which were committed during the whole year. Then their souls will be released from that burden, and being cleansed, will attain the holy day of the Resurrection and without condemnation, receive the Holy Mysteries, having become a new person through repentance in this holy fast".
