Q. (Do you have to save articles of Torah…) How about wedding and bar mitzvah invitations that have pesukim in them?
A. See prior question. The answer would be similar if they contain psukim. It is interesting to mention that Rav Pealim (Y.D. 4:32) maintains that the invitations should not be printed in regular Ksav Ashuris at all, as it possesses holiness; rather other script such as Rashi or other font variations should be used. However Ksav Sofer (E.H. 22) disagrees and mentions that his father the Chasam Sofer would send invitations in Ksav Ashuris. Be'er Moshe 3:183) explains that the Chasam Sofer had specifically in mind that no kedusha should descend on the writing of the invitations.
It should be mentioned too, that many Poskim advise that Hashem's names, psukim or detailed halachik instructions should not be printed on emblems, flags or badges, tz'daka receipts, labels of produce and wine bottles. (Horav Nissim Karelitz Shlit'a and others quoted in Ginzey Kodesh 9:1 and 12:9)
Horav Shlomo Miller's Shlit"a opinion is that there is room for leniency on psukim written on invitations, since they are included to effect blessings and not for the purpose of Torah learning. This seems to be the accepted custom today.
