In November 2014, the Archdiocese announced that the Church of Our Lady of Peace was one of 31 neighborhood parishes which would be merged into other parishes.[5] Our Lady of Peace was to be merged into the Church of St. John the Evangelist at 348 East 55th Street.[6]
In February 2017, the Archdiocese with the blessing of Pope Francis, announced an agreement to sell the church to the Egyptian Christian Coptic Orthodox Church community.[7] It then became St. Mary & St. Mark Coptic Orthodox Church.[8] The first Coptic worship service was on March 5, 2017.
