Mid-Pentecost

The fifty days following Pascha until Feast of Pentecost are known as the period of the Pentecostarion. At the Mid-point between these great feasts of Pascha and Pentecost, on the twenty-fifth day, which is always Wednesday, is one of the most beloved feasts for the most devout Orthodox Christians known as Pentecost. The mid-point of the Pentecotarion enlightens us regarding the theme of the fifty days following Pascha which is the acquisition of the Holy Spirit poured out as a gift upon all the faithful who partake of the living water which is Christ Himself. The central theme is therefore water, because it is the central theme of the Gospel of John which we read in its entirety during the Pentecostarion and which naturally flows into the Acts of the Apostles which is also read during this period in its entiretly.

The Fathers teach us that the feast of Mid-Pentecost stands in the middle of the fifty-day period from Pascha to Pentecost as a mighty flowing river of divine grace which have these two great feasts as its source. Pascha and Pentecost are united in Mid-Pentecost. Without Pascha there is no Pentecost and without Pentecost there is no purpose to Pascha.
The Feast of Mid-Pentecost is celebrated for an entire week unitl the following Wednesday, making it an eight day feast.The theme of the feast honors Christ as Teacher and Wisdom as He reveals Himself between the stories of the Paralytic and that of the Blind Man. During this time we are told: "Now about the middle of the feast Jesus went up into the temple, and taught...Jesus answered them, and said, 'My doctrine is not mine, but his that sent me. If any man will do his will, he shall know of the doctrine, whether it be of God, or whether I speak of myself'" (John 7:14-30). The icon for this feast depicts the young Jesus teaching the elders in the Temple (Luke 2:46, 47) at which time Jesus first revealed Himself as a teacher or rabbi. Traditional Orthodox icons will depict Jesus as larger than the elders, showing his superior spiritual status. (Mystagogy)
