Also among man's rights is that of being able to worship God in accordance with the right dictates of his own conscience, and to profess his religion both in private and in public. According to the clear teaching of Lactantius, "this is the very condition of our birth, that we render to the God who made us that just homage which is His due; that we acknowledge Him alone as God, and follow Him. It is from this ligature of piety, which binds us and joins us to God, that religion derives its name.'' (l0) Hence, too, Pope Leo XIII declared that "true freedom, freedom worthy of the sons of God, is that freedom which most truly safeguards the dignity of the human person. It is stronger than any violence or injustice. Such is the freedom which has always been desired by the Church, and which she holds most dear. It is the sort of freedom which the Apostles resolutely claimed for themselves. The apologists defended it in their writings; thousands of martyrs consecrated it with their blood."11Encyclical letter "Libertas praestantissimum," Acta Leonis XIII, VIII, 1888, pp. 237-238. 10Divinae Institutiones, lib. IV, c.28.2; PL 6.535.
Human beings have also the right to choose for themselves the kind of life which appeals to them: whether it is to found a family—in the founding of which both the man and the woman enjoy equal rights and duties—or to embrace the priesthood or the religious life.12Cf. Pius XII's broadcast message, Christmas 1942, AAS 35 (1943) 9-24.
The family, founded upon marriage freely contracted, one and indissoluble, must be regarded as the natural, primary cell of human society. The interests of the family, therefore, must be taken very specially into consideration in social and economic affairs, as well as in the spheres of faith and morals. For all of these have to do with strengthening the family and assisting it in the fulfilment of its mission.
