How have you processed the conflicts and trials endured by the Church, or caused by its members? What does it mean to be 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.”
