By Marco Tosatti, Church Militant - Archbishop Viganò: The concordat between the Holy See and the Italian State recognizes that the Church has, as its "native right," full freedom and autonomy in carrying out her ministry, which is given proper social and public expression in the celebration of Holy Mass and the administration of the sacraments. No authority may interfere in this ministry, not even with the consent of Church authority, which is not the master of the sacraments but rather the administrator of the grace conveyed by them.
