18 Venerable Brethren and beloved sons, while you entwine new flowers of supplication by reciting your Rosary, do not forget those who languish miserably in prison camps, jails, and concentration camps. There are among them, as you know, also Bishops dismissed from their Sees solely for having heroically defended the sacred rights of God and the Church. There are sons, fathers and mothers, wrested from their homes and compelled to lead unhappy lives far away in unknown lands and strange climates.
