- Question: Why should the sheliach tzibur not say his silent devotion when a minor holding a sefer Torah makes up the tenth man of the minyan and he only recites the repetition out loud?
A. The Mishna Berura (55:4:24) Brings a view that in emergency purposes one can use one child below bar mitzvah to make a minyan for barchu, kaddish, and kedusha. But not Mourners Kaddish for after Aleinu. He brings down that now a days they used this leniency if the child is holding a sefer Torah but he says many later poskim are stringent even for emergency purposes.
B. Rav Moshe Feinstein zt”l (Igros Moshe, Orach Chaim volume 2, chapter 18) ruled that if one does use this leniency the one leading the service should not say the Shemone esray twice, once to himself and once out loud.
Answer: In order to avoid saying brachos levatala, unneeded blessings, according to the view that this leniency does not work. So he just says the shemone esray once which counts for his personal obligation as well.
