ATLANTIC HIGHLANDS -- The Rev. Michael Riley will observe Reformation Sunday at the First Presbyterian Church this week with a sermon on the four pillars upon which the Reformed Protestant faith rests: Christ alone, Grace alone, Scripture alone, Faith alone.

   His sermon at the 10 a.m. worship service is entitled "O 'Sola' Mio."

   The occasion will also be marked by a bagpipe performance in the traditional of the Church of Scotland, the mother church of Presbyterianism, to which the public is welcome.

   The pastor also will continue his "mystery bag" children's sermon series during which youngsters try to "stump the pastor" by placing personal "treasures" submitted in brown paper bags. Riley then creates a message from the contents of the bag.

   Sunday School, which is open to all area youngsters, begins following the children's sermon.

   The adult choir, which is seeking new members, will also sing during the service. It rehearses at 7:30 p.m on Thursdays at the church.

   The pastor's weekly Genesis Bible Study is held at 7:30 p.m. each Wednesday and is open to the public.

   Riley, pastor since April, is an ordained minister and a columnist, staff writer and editorial writer at the Asbury Park Press. His column, "Only Human," appears in The Press on Fridays.

   The 121-year-old, handicapped accessible church at Third and E. Highland Aves., offers extra parking in a new municipal lot next to the Christian Education Building on Highland avenue.

   Child care for four-year-olds and younger continues to be provided during the regular worship service.
