Mishneh Torah, Prayer and the Priestly Blessing

Congregational prayer is always heard [by the Almighty]. Even if there are sinners among them, the Holy One, blessed be He, does not reject the prayer of a multitude. Hence, a person should associate himself with the congregation, and never recite his prayers in private when he is able to pray with the congregation. One should always attend Synagogue, morning and evening; for only if recited in a synagogue, are one's prayers heard at all times. Whoever has a synagogue in his town and does not worship there is called a bad neighbour.
