CIC 694 Water. The symbolism of water signifies the Holy Spirit’s action in Baptism, since after the invocation of the Holy Spirit it becomes the efficacious sacramental sign of new birth: just as the gestation of our first birth took place in water, so the water of Baptism truly signifies that our birth into the divine life is given to us in the Holy Spirit. As “by one Spirit we were all baptized,” so we are also “made to drink of one Spirit.”1 Thus the Spirit is also personally the living water welling up from Christ crucified2 as its source and welling up in us to eternal life.3

CIC 762 The remote preparation for this gathering together of the People of God begins when he calls Abraham and promises that he will become the father of a great people.4 Its immediate preparation begins with Israel’s election as the People of God. By this election, Israel is to be the sign of the future gathering of All nations.5 But the prophets accuse Israel of breaking the covenant and behaving like a prostitute. They announce a new and eternal covenant. “Christ instituted this New Covenant.”6

CIC 2121 Simony is defined as the buying or selling of spiritual things.7 To Simon the magician, who wanted to buy the spiritual power he saw at work in the apostles, St. Peter responded: “Your silver perish with you, because you thought you could obtain God’s gift with money!”8 Peter thus held to the words of Jesus: “You received without pay, give without pay.”9 It is impossible to appropriate to oneself spiritual goods and behave toward them as their owner or master, for they have their source in God. One can receive them only from him, without payment.
