A Páscoa (do Hebraico Pessach, "Passagem") "Eis o Cordeiro de Deus, Aquele que tira o pecado do mundo (João, 1:29)" Na Páscoa celebramos a Ressurreição de Jesus Cristo. (Vitória sobre a morte.)
Pascha (from Hebrew Pessach, “Passageâ€) “Here is the Lamb of God, The one who takes away the sins of the world, (john 1:29)†At Easter we celebrate the Resurrection of Christ (victory over the death)
Remarks about the translation
Easter is also called Pascha, according to Hebrew "pessach" I choose this one in the first sentence. http://en.wikipedia.org/wiki/Easter
