Ron,
I think I might have some useful thoughts about your concerns. There are different degrees of understanding, and I think it would help to go back again to those encyclicals and read them in context. The Church never taught that some of the things you say…
It’s important to understand what the teaching is besides just the verbatim words. We are taught over and over again in the scriptures that faith is gain by listening (not by reading) and that we cannot learn unless there is someone to teach us.
To say one thing and then say the opposite is not a fuller understanding. It’s a contradiction. Here are some examples:
“Slavery itself, considered as such in its essential nature, is not at all contrary to the natural and divine law, and there can be several just titles of slavery and these are referred to by approved theologians and commentators of the sacred canons… It is not contrary to the natural and divine law for a slave to be sold, bought, exchanged or given”.
Pius IX (Instruction 20 June 1866 AD). J.F.MAXWELL, ‘The Development of Catholic Doctrine Concerning Slavery’, World Jurist 11 (1969-70) pp.306-307…
“Whatever is opposed to life itself, such as . . . arbitrary imprisonment, deportation, prostitution, the selling of women and children, and slavery . . . all these things and others of their like are infamies indeed. They poison human society and are a supreme dishonour to the Creator . .
Human institutions, both private and public, must labour to minister to the dignity and purpose of the human person. Let them put up a stubborn fight against any form of slavery and safeguard the basic human rights under any political system.”
Vatican II, Gaudium et Spes (AD 1965) § 27, 29.
“[It is an error to say that] every human being is free to embrace and profess that religion which, led by the light of reason he/she believes to be true”.
Pius IX Syllabus of Errors (1864 AD), Denz. 1715.
“This Vatican Synod declares that the human person has a right to religious freedom. This freedom means that all people are to be immune from coercion on the part of individuals or of social groups and of any human power, in such wise that in matters religious no one is to be forced to act in a manner contrary to his/her own beliefs.”
Vatican II, Dignitatis Humanae (1965 AD) § 2
“[It is an error to say that] it is praiseworthy that in certain Catholic countries it is provided for by law that people who immigrate from outside may publicly exercise their own form of worship.”
Pius IX Syllabus of Errors (1864 AD), Denz. 1778.
“Religious bodies rightfully claim freedom to govern themselves according to their own norms, honour the Supreme Being in public worship, assist their members in the practice of the religious life, strengthen them by instruction and promote institutions by which they may join together for the purpose of ordering their own lives in accordance with their own religious principles.”
Vatican II, Dignitatis Humanae (1965 AD) § 5.
