Mid-Pentecost is the twenty-fifth day of Pascha, half-way to the Great Feast of Pentecost on the fiftieth day. On this day we commemorate Christ's teaching in the temple "in the midst of the Judaic feast" (John 7:14-30).  Although we were unable to have services on Wednesday 10 May, the day of Mid-Pentecost itself, on the eve of the feast we had Matins followed by the customary blessing of water.  The blessing of water occurs on this day as a sign of the grace of the Holy Spirit and with reference to the "living water" promised by our Lord Jesus Christ to all that believe in Him (John 7:37-38).
