St. Mary's Church is a Catholic parish located in Ballston Spa, New York. It is located within the Roman Catholic Diocese of Albany. Father Thomas J. Kelly is the current pastor. St. Mary's is the fourth oldest parish in the Diocese. St. Mary's of Ballston Spa is partnered with St. Mary's of Galway, after the pastor at St. Mary's of Galway died and no replacement was available.
Father Thomas J. Kelly is the current pastor for Ballston's St. Mary and will replace the pastor of St. Mary's of Galway after their passing. 
I think it should be neither definitely correct nor definitely incorrect because it states that the 2 churches partnered after the pastor died and no replacement was chosen. It could be assumed that Father Kelly would replace the duties of the late pastor as both churches have partnered, but also potentially not because it would require him to be at 2 different Churches which isn't always possible suggesting he might not be a replacement.
