A chorale prelude to "Wie gross ist des Allmächt'gen Güte" is not something you come often across. And there appear to be several melodies in use for this particular choral. As far as I know Oley is the only one who uses this melody. An exeption might be the choral prelude by Johann Adam Hiller, but I've only seen the first two bars of that one. So this composition is a bit of a rare one. Oley writes a nicely flowing three part texture that seems to me to focus more on the 'good' (Güte") than ond the great ('gross').
The recording was done with the Hauptwerk software and the sample set of the Holzey organ of St. Peter and Paul in Weissenau by Prospectum (https://www.prospectum.com/index.php?language=english&id1=2&id2=9).
