Various forms of sacramentals
Among sacramentals blessings (of persons, meals, objects, and places) come first. Every blessing praises God and prays for his gifts. In Christ, Christians are blessed by God the Father "with every spiritual blessing." This is why the Church imparts blessings by invoking the name of Jesus, usually while making the holy sign of the cross of Christ.
