On June 4, 2023, the day of Pentecost, a missionary youth evening dedicated to the feast of the Holy Trinity was held in the parish hall of St. Nicholas Patriarchal Cathedral in New York. First, the rector of the cathedral, Archpriest Igor Vyzhanov, greeted everyone. Then the “Brain Ring” quiz began. The young people answered questions about the Descent of the Holy Spirit upon the apostles or otherwise related to the Holy Trinity. The host supplemented the answers with interesting facts. Between the three rounds of the game, everyone sang traditional Trinity folk songs and took part in contests. The young men made bouquets, as has been customary since ancient times on Pentecost, and gave them to the charming young women at the evening. And the young women prepared treats traditional in Rus’ since antiquity. One of the Brain Ring questions was devoted to the most ancient Slavic dance — the khorovod, the round dance usually performed by young women and men both on Trinity and on other feasts. After the game, all participants tried performing this folk dance themselves. The evening ended with a festive meal.
