שאלות ותשובֿות אויף תהילים 119:162

And he answered: This is the practice in our place on the day of a circumcision - we pray penitential prayers and the confession; but we do not say, "And He is merciful" or supplications. And the custom of our ancestors is Torah. And the commandment of circumcision was accepted with joy and we still do it with joy, as it is written (Psalms 119:162), "I rejoice in Your word." Hence we are not accustomed to say, "And He is merciful" or supplications. And it is enough for me that we leave a little, such that we do not have to completely interrupt the penitential prayers, the confession and "God of lasting patience?" And the prayer leader recites a blessing over the wine, but he does not taste it. And the custom of our ancestors is Torah - that he does not need to taste it on a fast day, and he does not give it to the child, since he will come to be drawn in [to sin when he is older], but he rather leaves it until the evening. And the infant's mother does [not] drink it, as she needs to continue the fast. For [otherwise], even though we say that the one who recites the blessing needs to taste, it is fine when an other will taste it. As we ask [in the Talmud] about Yom Kippur, "Let him say [the blessing on] time over a cup [of wine] like on other holidays and let him give it to a child," and we answer, "Since he will come to be drawn in." The reason is that he will be drawn in. But where there is no concern for being drawn in, it is fine when an other tastes [it]. And we do not recite the blessing over time over a cup [of wine], like on other holidays when it must be drunk for the kiddush of that day. And it cannot be said that he should leave it until the evening of the conclusion of Yom Kippur, as it is not possible.
