Pentecost
The feast celebrating the descent of the Holy Spirit on the disciples.
Pentecost is the Christian feast celebrating the descent of the Holy Spirit on the disciples fifty days after Easter, commemorated on the seventh Sunday after Easter (or, in Orthodox tradition, the seventh Sunday after Pascha). The feast takes its name from the Greek pentekoste, fiftieth. Pentecost is sometimes called Whitsunday in older Anglican usage. It is observed liturgically with red vestments (signifying the tongues of fire that descended on the disciples), specific scripture readings (especially Acts 2), and (in many parishes) the singing of "Veni Creator Spiritus" or "Veni Sancte Spiritus." Pentecost closes the Easter season; Ordinary Time resumes the following day.
