Regarding the mention of the food being eaten in the name of God and reciting the blessing on Shabbat,
The Rema wrote, “O”C 60 Ra”A 66:11, that one who eats on Shabbat eve near night and recites the blessing of food after Shabbat has begun, and that he does not mention Shabbat after the beginning of the meal, and so on, etc., Aisha.
And here is the Grek “A” A” H 6662, the small law that he ate near the night of his greatness and blessed the food blessing and within a certain time period until the meal became large, is it not necessary to repeat and bless the food blessing, since the food blessing that he blessed in his smallness was only among the rabbis and now is obligated by the Torah, and the rabbis do not grant to the learned Dauraita a duty to bless the food blessing as long as he is full because of the meal he ate earlier, and apparently 22. May he not have opposed the law of the Rada that the Rema ruled that one follows after the main part of the meal and not after the time of the meal, even if one does not eat anything after dark [A” Sh in the Mishnah], because the time of the meal is after dark, and so what is the reason that one is not obligated to add the Rada at this time?
I thought to myself that the mention of Shabbat and the Lord’s Prayer in the blessing of food when the next day arrives has nothing to do with the question of Reka.
In mentioning Shabbat, etc., the question is how to recite the blessing so that there is no contradiction within the blessing for food, because one recites the blessing on Shabbat but eats on a Sabbath. The mention of Shabbat, Yom Kippur, and Racha is not part of the blessing of gratitude for food. Rather, it is added to the blessing for food.
The question of Reka is for someone who was not obligated and ate and is now obligated, since the obligation to recite the blessing of food is until digestion, whether the blessing after eating is for what is currently full, and therefore one is a minor and a stranger obligated by the Torah. Or is the blessing a kind of teshlomin for eating and if one recited a blessing over it, one does not need to recite the blessing again.
