Christ loved the church, by giving himself on the cross. And this means that the church is holy because she comes from God, who is holy; he is faithful to her and does not abandon her to the power of death and of evil. She is holy because Jesus Christ, the holy one of God, is indissolubly united to her; she is holy because she is guided by the Holy Spirit who purifies, transforms, and renews. She is not wholly by her own merits. It is not we who make her holy. It is God, the Holy Spirit, who in his love makes the church holy.
– Pope Francis
