Along with Christmas and Easter, Pentecost recognizes a major milestone in the Christian story. It was on that day, fifty days after the resurrection of Christ, that the church was born through the fire of the Holy Spirit. Although Pentecost does not enjoy the popular embellishments of Santa and the Easter Bunny so loved by florists and candy makers everywhere, it does deserve the energy and attention of believers. Pentecost and its call to be witnesses can enlighten and clarify the church's sense of identity and mission. In this one-session study for adults, participants will discuss the nature of the Holy Spirit and the meaning of being a witness.
