Celebrate Pentecost at the Church of St. Paul! Posted on May 16, 2018 by Leslie RMay 16, 2018 Bring Red Geraniums to Church this Sunday The Church of St Paul is carrying on its tradition of asking members of the congregation to bring red geraniums to church on Pentecost Sunday – May 20th. They will be used in planters and the garden. For those wondering “why red?”. That’s because red is the liturgical colour for Pentecost.
