Do Methodist elders still wear red on Pentecost? I left for Orthodoxy years ago due to an abusive priest at one local parish getting on my case because I was a traditionslist, and the parish where I was baptized abandoning the organ and hymns for a praise band, but I still love what Methodism was to me growing up.
One bit of culture shock: in the Eastern Orthodox, the liturgical color for Pentecost is usually green, and some parishes only break out the green vestments twice a year, the ither time being Palm Sunday. The church is decked out in greenery for Pentecost. The theology is that the leaves represent the tongues of fire.
And another: in the Syriac Orthodox church, of which I am proud to be a member, there are no formal liturgical colors but red, gold and white predominate. The Pentecost service is a lot of fun however because palm fronds are immersed in Holy Water and then the priest attacks members of the congregation with the fronds. This is not like the Asperges Mea at the start of a Roman Catholic Latin mass, where you get likely sprinkled, but rather a full on, Splash Mountain style dousing. It is very popular with the laity who encourage the priest to douse them. In the native lands of the Syriac and Armenian Orthodox (Syria, Turkey, Iraq, Lebanon and Israel/Palestine), there is a popular custom among the Christians to throw buckets of water on each other after church on Pentecost.
