The word “Pentecost” comes from the Greek term “pent?kost?” which means “fiftieth.” Pentecost finds its roots in the Jewish holiday of Shavuot, which takes place 50 days after Passover and celebrates the giving of the Torah to Moses on Mount Sinai. Pentecost is a significant Christian holiday commemorating the Holy Spirit’s descent upon the apostles of Jesus Christ, marking the birth of the Christian Church.
