The Apostles' Creed

'I believe in God the Father Almighty; Maker of heaven and earth.
And in Jesus Christ his only Son our Lord; who was conceived by the Holy Spirit, born of the virgin Mary, suffered under Pontius Pilate, was cruicified, dead and buried; the third day he rose from the dead; he ascended into heaven; and sitteth at the right hand of God the Father Almighty; from thence he shall come to judge the quick and the dead.
I believe in the Holy Spirit, the holy catholic Church; the communion of the saints; the forgiveness of sins; the resurrection of the body; and the life everlasting. Amen.

Who/what are the quick??
