Confirmation was at first excluded from the synagogue, because, like every innovation, it met with stern opposition from more traditional rabbis. Gradually, however, it found more favor; Hebrew school classes were confirmed together, and confirmation gradually became a solemn and celebration at the synagogue. In 1822 the first class of boys and girls was confirmed at the Hamburg Temple, and in 1831 Rabbi Samuel Egers, a prominent traditional rabbi of his time, began to confirm boys and girls at the synagogue of Brunswick. While in the beginning some Shabbat, frequently during Chanukah or Passover, was selected for confirmation, it became increasingly customary, following the example of Egers, to perform the ceremony during the biblical festival of Shavuot ("Feast of Weeks"). It was felt that Shavuot was well suited for the rite, as it celebrated the occasion when the Israelites on Mount Sinai declared their intention to accept the yoke of God's Law, so those of every new generation should follow the ancient example and declare their willingness to be faithful to the Sinaitic covenant transmitted by their ancestors.
