Jesu, meines Glaubens Zier

Jesu, meines Glaubens Zier is a German Lutheran hymn by Gottfried Wilhelm Sacer, first published in 1661. Its hymn tune, Zahn No. 6453, was first published in 1714, in Freylinghausen's hymnal. In 1736 the hymn was adopted in Schemellis Gesangbuch, with a figured bass accompaniment which may have been contributed by Johann Sebastian Bach (BWV 472).

The tune is also known in English due to its presence in the 1906 English Hymnal and its 1986 successor, where it appears to "It is finished! Christ hath known", a Passion text by Gabriel Gillett written for the 1906 publication and based on Jesus' dying words, per the Gospel of John, "tetelestai" ("It is finished!"), which have inspired many other hymns.
