Sitting down at the shul kiddush

Hi,

Is there a preference for sitting or standing while the Rav recites kiddush at the shul kiddush?

Ideally, one should recite kiddush on behalf of another only when both parties are seated at the same table, in order to establish and define the group that is fulfilling its mitzvah together. This applies to havdalah as well. However, if a group of people gathers in a clearly defined space with intent to perform a mitzvah as one, then standing is acceptable.

In another halachah related to sitting and kiddush, one should sit while reciting al hamichyah after eating cookies or cake, as one does for the berachot of hamotzi and birkat hamazon. This is meant to display respect for the berachah, and to aid concentration. However, one who eats while walking to a destination may stand while reciting the berachah; this is not disrespectful, because the eating itself takes place while standing, and because sitting down for the berachah would cause a distracting delay in the trip.

(Berachot 43a; Tosafot ibid. ho'il; Shulchan Aruch Orach Chaim 167:11, 183:9-10; 184:; 213:1; Mishneh Berurah 271:46; Aruch haShulchan Orach Chaim 271:24. And see Rivivot Ephraim 1:151:6)

Have a great day,
Mordechai
