Now, it is absolutely certain that the invisible Church can, in some partcular circumstances, extend beyond the boundaries of the visible Church; and likewise, it is possible for a person who is a member of the visible Church to not be a member of the invisible Church. Let me give a few example to try to clarify that:
Let’s say that a person was baptized Catholic. Every week they attended Mass, gave money to the parish, went on “pro-life” rallies, and even tried to bring others into the Church, yet knowingly rejected a dogma of the faith, such as transubstantiation, or papal infallibility. Now, such a person would not be a Catholic. They would appear to be Catholic, but in reality - on the “invisible level” - they would not be Catholic, but a heretic. They may be a member of the visible Church, and may certainly appear to be Catholic, but they would not be. Now, most likely, only God would know that because “man seeth the things that appear, but God beholds the heart”.
On the other hand, let’s say that a child of 5 was validly baptized by a heretical minister of a Protestant denomination. Even if that child had never stepped foot into a Catholic Church, they would be just as Catholic as any other Catholic Child. They would be a member of the invisible Church, but not the visible Church, since they had never stepped foot into a Catholic Church and were not registered as a member of the true Church. Such a person is a member of the invisible Church.
Now, let’s take another example - one step further: let’s say that an adult went through a conversion. They believe explicitly in the Trinity and Incarnation (which most theologians, such as St. Thomas, say is necessary for salvation), and, although they may not explicitly believe any other dogma (since they are “invincibly ignorant” of them), they also do not reject any dogmas, which means they are not actual heretics, but at most only a “material heretic”. Now, if such a person was baptized, they too would become a member of the invisible Church, but since they were baptized outside of the visible Church (by a heretical sect), they would not be a visible member of the Church.
We can see from these examples that, although the Church consists of both the visible and invisible, it can and does happen that a person may not be a member of the visible Church, yet nevertheless be a member of the invisible Church, just as a person may be a member of the visible Church, yet not be a member of the invisible Church.
Although this distinction between the visible and invisible Church may confuse some, since most today focus on the subjective exception, rather than the objective rule, it does help in dealing with those who allow no exception to the doctrine of EENS, which they interpret as meaning that a person must be a member of the visible Church to be saved, and allow absolutely no exceptions.
Of course, only God knows “whether, or which human beings”

belong to the invisible Church and not the visible Church, for “man seeth the things that appear, but God beholds the heart”.
What are your thoughts on that?
