Tritt auf die Glaubensbahn (Step upon the path of faith), BWV. 152, is a cantata by J.S. Bach, composed in Weimar for the Sunday after Christmas and first performed on 30 December 1714. The cantata is intimate chamber music for only two voices, soprano and bass, and four solo instruments. The opening sinfoniain two sections is reminiscent of a French overture, which Bach had used with a meaning in Nun komm, der Heiden Heiland, BWV. 61, a few weeks earlier. The theme of the fugue is similar to that of Bach's fugue for organ, BWV. 536. The cantata is scored for two soloists—soprano and bass—and four solo instruments: recorder, oboe, viola d'amore, viola da gamba and basso continuo. Bach himself wrote in the extant score "Concerto à 1 Flaut. 1 Hautb. 1 Viola d'Amour. 1 Viola da Gamba. Sopr. è Baßo coll' Organo." The cantata is Bach's only one using the viola d'amore.
