95 Accordingly We, as representatives on earth of Him Who was proclaimed by the Prophet "Prince of Peace" ( Isaias ix. 6) appeal to the rulers of the peoples, and to those who can in any way influence public life, to let the Church have full liberty to fulfill her role as educator by teaching men truth, by inculcating justice and inflaming hearts with the Divine Love of Christ.
