Whoa…now I’m really confused. Again. Doesn’t this illustrate my quandary–we must believe the Church, even when she’s mistaken vs believe only things that are sententia certa
Sententia certa is not infallible or immutable.
De fide dogmas are. thus, you still have to distinguish the teaching into two categories. However, the categories are NOT infallible and fallibe. Instead the two categories are 1) doctrine or 2) speculative theology.
You must give your religious assent to the non-infallible
doctrines (
sententia certa) of the Catholic Church. You must give your assent of faith to those doctrines which are also
dogmas (
de fide) of the Catholic Church. The difference is that the lack of religious assent is a sin against charity, and lack of assent of faith is a sin against faith. It’s a rather academic theological difference, as both require the assent of intellect and will. Whether it is a sin against charity of a sin a faith…it is still a sin.
Nonetheless, theologians also engage in
speculative theology, which is often also presented by the
Teaching Church, to which we are not bound to give our religious assent. We can discern that which is speculative to that which is certain from the context of the teaching, the manner it which it was taught, and the words used in teaching it.
For example, the Jesuits taught me the one theory of the understanding of grace, freewill, and predestination. However, the Dominicans teach a different theory. Both are in accord with Catholic doctrine, yet each theory disagrees with the other. I am not bound by ecclesiastical discipline to assent to one or the other, or either. Some Church teachings are simply “common teaching” (
sententia communis) which are still within the field of free opinion.
The other example I gave earlier was St. Augustine’s view that those who die in original sin only would suffer both pain of torment (
peona sensus) and loss of the Beatific Vision of God (
poena damni), while St. Thomas Aquinas taught that only the loss of Beatific Vision occurs, and they actually life in natural happiness without torment, yet still consisting of the lack of supernatural Beatific Vision of God. These are among the
common teachings of the Church, but are not among the
certain teachings which are doctrinal, properly so-called.
I am not an uneducated person-…I certainly cannot tell the difference between common teaching" (sententia communis) and “certain teaching” (sententia certa) regarding current issues such as stem cell research and homosexual unions…
That’s why we have a **
living magisterium . **We are not left to our own private lights to understand what is doctrine and what is not. We can simply ask our pastor, our bishop, our pope. They can tell you if teaching X is speculative or binding doctrine or dogma. That’s why they went to seminary.

Have you discussed this with your pastor or bishop yet? If so, what did they tell you?
Now, there are not a small number of dissenting clergy, so you still have the personal responsibility to listen to your pastor, and if he is teaching you something contrary to your bishop, then you might seek clarification from your pastor and bishop. Likewise regarding your bishop, if he should teach something contrary to Pope Benedict XVI. In the final analysis, you have recourse to a
living magisterium and need not rely upon your ability to understand and apply the principles of Catholic dogmatic theology with regard to ecclesial texts , for which you probably have not been taught.
Regarding homosexual unions and stem-cell research…
Find out what your pastor and bishop teach, and the
manner in which they teach it. Is it presented as certain teaching, or do they say “some assert this, some assert that…?”
I am a post-graduate student in theology, so I am somewhat familiar with the principles of Catholic dogmatic theology. Consequently, with regard to Catholic teaching on stem-cell research and homosexual unions, we can further discuss these using the magisterial texts and it may become more clear the certainty of the teaching given the manner in which the teaching has been promulgated, and context, frequency and words used to teach it.
As for immovable earth and it’s place in Catholic teaching. I have never seen or heard my pastor, my bishop, or my pope assert such a thing. If it is Catholic doctrine, they are doing a good job of keeping it a secret.
