Today is World Communion Sunday, and United Methodists, in conjunction with other denominations and believers worldwide, participate in communion to recognize our unity in Jesus Christ, our Lord and Savior. Rev. Ron Bartlow begins a new series on "Our Community". This week's sermon, "All Are Welcome", recalls the origins of the sacrament of Holy Communion, as told in Mark 14:12-26 and 1 Corinthians 11:23-26. Holy Communion is rooted in the Passover. As at the Passover, in Holy Communion, all are welcome and all are potentially saved. Why potentially? Because we are invited into God's activity and work of salvation.
