The Gospel Readings for Sunday is John 7:37-52 & 8:12, The Promise of the Holy Spirit. The Gospel reading for Pentecost includes: “If any man thirst, let him come unto me, and drink” and “I am the light of the world: he that followeth me shall not walk in darkness, but shall have the light of life.” We must learn to thirst for the Holy Spirit and for light. How do we learn to thirst? We must search for knowledge about our weaknesses, and with faith to learn to walk in the light. This does not just happen, as we go through life in order to have the Holy Spirit abide in us, since He is the Spirit of Truth, we must live according to the truth.
Feast occurs 50 days after Pascha and commemorates the descent of the Holy Spirit upon the Apostles of Christ after His Resurrection. The liturgical color used at Pentecost is green. One of the popular Pentecost customs is to put up greenery, particularly from the linden tree. In the Slav tradition, Pentecost is often called Rusalija. The displaying of greenery is given a Christian meaning, representing new life through the Holy Spirit. In the evening of Pentecost Sunday a special Vespers is celebrated, called the Kneeling Prayer. This is a Vespers service to which are added three sets of long poetical prayers, the composition of Saint Basil the Great, during which everyone makes a full prostration.
Pentecost Monday is also known as “Monday of the Holy Spirit” or “Day of the Holy Spirit” and is the first day of the after feast of Pentecost, being dedicated specifically to the honor of God the Holy Spirit and particularly to the historical event of His descent on the holy apostles on Pentecost. The third day, Tuesday, is called the “Third Day of the Trinity. The After-feast of Pentecost lasts for one week and is festive, during which fasting is not permitted. Then we return to “ordinary time” of the Church year.
