Calvin defined a sacrament as an earthly sign associated with a promise from God. He accepted only two sacraments as valid under the new covenant: baptism and the Lord's Supper (in opposition to the Catholic acceptance of seven sacraments). He completely rejected the Catholic doctrine of transubstantiation and the treatment of the Supper as a sacrifice. He also could not accept the Lutheran doctrine of sacramental union in which Christ was "in, with and under" the elements. His own view was close to Zwingli's symbolic view, but it was not identical. Rather than holding a purely symbolic view, Calvin noted that with the participation of the Holy Spirit, faith was nourished and strengthened by the sacrament. In his words, the eucharistic rite was "a secret too sublime for my mind to understand or words to express. I experience it rather than understand it."; ; ; ;
