2. Attending a Bris:[1]

It is a Mitzvah to attend a Bris.[2] Whoever attends a Bris his sins are atoned for.[3] Whoever attends a Bris is considered that he has accepted the face of the divine presence.[4] Whoever attends a Bris receives an additional soul just like on Shabbos and Yom Tov. He merits to fulfill all the Torah.[5] One may even nullify Torah study for the sake of attending a Bris.[6]

One who is invited and does not participate:[7] Any individual who was invited to participate in the festive meal of the Bris, and does not participate in the eating is considered excommunicated in heaven. [This however only applies to the meal of the Bris, and not to the actual ceremony. Due to this, the father should not explicitly invite people to the meal of the Bris and should rather simply inform them of the time of the ceremony and the meal. Likewise, the Gabaiy of a shul should not announce that the father is inviting the congregants to the Bris, and rather he should simply state the time and location of the ceremony.[8]]
