Q. Is it ok for a woman to be included in the kiddush and homotzi of a man who isn’t shomer Shabbat yet? What about havdala?

A. The above should be avoided as it is possible that the man is not yet a proper believer in Hashem and his Torah. Since he does not keep Shabbos yet. His brochos woul in principle then be likely in vain.

On question 1641 regarding Kiddush for a not yet frum visitor, we wrote:
“Horav Shlomo Miller’s Shlit’a opinion is that indeed you can not be motzy or have someone comply with a mitzva by listening from another, if the listener does not understand the basic meaning of what is happening. Although he does not have to understand the translation of all the words being said aloud for his sake, he does have to comprehend and believe in the fundamentals and purpose and reason of what is being recited.”

See also question 533 regarding the blessing of “baruch sheptarani” recited by a non-religious yet father on the Bar Mitzva of his son.

Horav Yaakov Hirschman Shlit’a added that if the Bar Mitzva boy is not going to be an observant Yid, there is no meaning and purpose to this brocho. On the contrary, by reciting it, the father is only adding punishment to himself.
