II THE CHURCH IS HOLY
"The Church on earth is endowed already with a sanctity that is real though imperfect." In her members perfect holiness is something yet to be acquired: "Strengthened by so many and such great means of salvation, all the faithful, whatever their condition or state - though each in his own way - are called by the Lord to that perfection of sanctity by which the Father himself is perfect."
