The Confession Read
Private masses, or receiving this sacrament by a priest, or any other, alone; as likewise, the denial of the cup to the people, worshiping the elements, the lifting them up, or carrying them about for adoration, and the reserving them for any pretended religious use; are all contrary to the nature of this sacrament, and to the institution of Christ.— Westminster Confession of Faith, Chapter 29, Section 4
