Gradually, most of the Apostolic Churches “unpacked” this nucleus into its component celebrations, spreading throughout the winter calendar. For example:
The Christmas Fast [15 Nov – 24 December]:
The Byzantine six-week Christmas-Fast period is still in a period of development. The 1st, 2nd 3rd & 4th Sundays have Lucan Gospels with themes touching on social justice / God’s love for the poor. E.G.: in 1998: Lk 10: 25-37 (The Good Samaritan); Lk 12:16-21 (The Foolish Grain owner); Lk 13:10-17 (The Crippled Woman); Lk 17: 12-19 (The 10 Lepers).
| 2nd Sunday before Christmas | The Forerunners of Christ |
| Sunday before Christmas | The Genealogy of Christ |
The Season of the Epiphanies [25 Dec – 2 Feb]
| 25 December | The Nativity & Adoration by Magi & Shepherds |
| 25 Dec – 4 Jan | Fast Free period |
| 26 December | Synaxis of the Theotokos |
| 27 December | St. Stephen Protomartyr |
| Sunday after Christmas | The Righteous Ones: David the King, Joseph the Betrothed, and James, the Brother of the Lord |
| 1 January | The Circumcision |
| 6 January | Theophany (Baptism of Christ) |
| 2 February | Encounter in Temple (end of the Season of Epiphanies) |
As of the present, the Sundays after Christmas have not yet developed a fully set character as have the post-Paschal Sundays. The only fixed observances:
| Sunday after Christmas | Incarnation themes |
| Sunday before Theophany | Baptismal / Revelation themes |
| Sunday after Theophany | Baptismal / Revelation themes |
| Fourth Sunday of January | Commemoration of all the New-Martyrs & Confessors of the Communist Yoke (OCA) |
