The Synaxis of the Twelve Apostles is a feast day in the Byzantine Catholic Church that commemorates all of the twelve Apostles of Jesus Christ on one day. It is celebrated on June 30th, the day after the feast of Saints Peter and Paul. The Synaxis is an important feast day because it recognizes the unity and importance of the apostles in the early Christian Church. The apostles were the closest followers of Jesus and were chosen by him to spread his teachings and establish the Church. The Synaxis is also a reminder of the diversity of the apostles, who came from different backgrounds and had different personalities and strengths. For example, Peter was a fisherman, while Matthew was a tax collector. Despite their differences, the apostles worked together to spread the message of Christ and establish the Church. Although we remember each of the Twelve Apostles at different times throughout the year, this Friday we will celebrate a general remembrance for all of them with liturgical services and hymns that honor their contributions to the Church.
