The Church of St. Paul the Apostle is a Roman Catholic church located at 8-10 Columbus Avenue in the Upper West Side.
After the Ghostbusters went back into business in late 1989, Ray Stantz and Egon Spengler visited the Church of St. Paul the Apostle. They collected a sample of Psychomagnotheric Slime from the stairs outside. Ray and Egon knelt and squatted, respectively, near a black gate where a slime trail flowed past. Ray ladled the slime into a small plastic jar.
- Egon and Ray are also collecting Psychomagnotheric Slime from a pay phone on West 59th Street across from the 910 9th Avenue side of Coliseum Park Apartments. This location is a block over from the Church of St. Paul.
