I’ll try to reply to your posts later tonight, as I have a test to study for.
Take your time, brother. I know the stress of such things. I’ll be praying for you.
For now though, what is concupiscence?
Concupiscence, as defined by St, Athanasius (and, off the top of my head, St. Basil, as well - I’m sure there are others, but I can’t think of them right now), is the disordered use of reason that resulted from the Fall. As you had stated, humanity wants what is good. But since the Fall darkened our rational powers (i.e, our reason), then we wrongly choose (i.e., use our free will) evil for good. We THINK (because our rational mind has became disordered) that we are choosing good, but it is really, objectively evil in the eyes of God. For example, sensual pleasures such as fornication, or gluttony, or greed, etc.
Here is what the Catholic Catechism states:
2515. Eytmologically, “concupiscence” can refer to any intense form of human desire. Christian theology has given it a particular meaning: the movement of the sensitive appetite contrary to the operation of human reason. The apostle St. Paul identifies it with the rebellion of the “flesh” against the “spirit.” Concupiscence stems from the disobedience of the first sin. It unsettles man’s moral faculties and, without being in itself an offense, inclines man to commit sin.
By “inaccessible to humanity at any time” I mean a total depravity from Grace, in which fallen Man has zero access to Grace.
OK. No. This is the teaching of Calvinism, not St. Augustine nor the Catholic Church. The Catholic Church teaches, in line with Augustine, that humanity is indeed depraved, and depraved to a point that without Grace, he can never rise to the righteousness or holiness that is acceptable to God. The difference between the heresy of Total Depravity (taught by Calvinists) and the Catholic/Augustinian teaching, is that Total Depravity presumes that nothing of the human, not even the will, is involved in acquiring the initial Gift of Faith/Justification. In contrast, St. Augustine taught in several places that the Human Will is not lost despite the teaching on the necessity of Grace. That is the teaching of the Catholic Church - that human will can be aided by Grace to accept the initial Gift of Faith. In Catholic teaching, humanity is not so damaged that it cannot participate in its own salvation (with Grace, of course), before, during, and after the intial Gift of Faith/Justification.
This has been the constant teaching of the Catholic Church from the beginning. If you understand what I am saying, then we should be able to move on to the last of your three objections to the IC - namely, that Mary was without Original Sin. But this depends on your understanding of Original Sin, in light of my own responses to you.
Looking forward to our discussion later.
Abundant blessings (especially for your test),
