Names and titles of Jesus in the New Testament which rises in victory as the Resurrected Christ was employed in early Christology, e.g. in 375 Saint Augustine wrote: "Why a lamb in his passion? For he underwent death without being guilty of any inequity. Why a lion in his resurrection? For in being slain, he slew death." The Lamb of God title has found widespread use in Christian prayers and the "Agnus Dei" ("Lamb of God who take away the sins of the world have mercy on us; Lamb of God who take away the sins of the world grant us peace") is used both in liturgy and as
Agnus Dei (liturgy) the Roman Missal, § 83, states: "The supplication "Agnus Dei", is, as a rule, sung by the choir or cantor with the congregation responding; or it is, at least, recited aloud. This invocation accompanies the fraction and, for this reason, may be repeated as many times as necessary until the rite has reached its conclusion, the last time ending with the words "dona nobis pacem" ('grant us peace')." In Tridentine Requiem Masses, the first two invocations ended with "dona eis requiem" (give them rest) instead of "miserere nobis", and the last with "dona eis requiem sempiternam" (give them rest eternal).
