Hi - Just unsure which language is used. I can tell there's some Latin, but is there also Polish or German?

I don't need a translation, but it would be helpful to know the language used in the original document.
Here's a link to the record. It's the 1st entry on the upper left in the original manuscript document:

Simonem Szewel, „Deutschland, Preußen, Westpreußen, Katholische und Lutherisch Kirchenbücher, 1537-1981“

Thanks! - Maria ❤️
