Dr. Petuchowski explains the purpose of the leaflet in a postscript:
This prayer-leaflet is primarily intended for a group of Hebrew Union College students who meet every sabbath afternoon for extra-curricular (noncredit) Torah study. It is fitting, therefore, that their weekly gatherings should begin with the Sabbath Minḥah Service; and it was for that purpose that this leaflet was compiled. The service is conducted entirely in Hebrew and in the traditional nusaḥ. We have omitted only the various repetitions as well as the prayer for the restoration of the sacrificial service. (But we have retained the place of Zion as the symbol of the messianic hope.) In the ‘Alenu prayer, we have preferred a positive formulation of the “Election of Israel” to the traditional negative one. . . . → Read More: Tefillah Minḥah l’Shabbat (Jakob J. Petuchowski, 1966)
