Collection of parish records may have been assigned to the wrong church, or there was a name change
It looks like Film 1203433 (DGS 102,398,042) - Heiraten 1803-1825 (l. & r. S.) (and possibly the other films 1203429-1203434, 1340921-1340922) was assigned to the wrong church. In the catalog they are associated with the Evangelische Kirche Sankt Andreas Erfurt.
The title page for the marriage book (image 292, r.S.) identifies the church as Lutheran church "S. Andrea et Mauritii." While S. Andrea appears at the top of most of the following pages, Andrea and Mauritii also appears. I found a Lutheran St. Mauritius and Andreas church in Kleinneuhausen.
