The Holy Spirit, according to Catholic definition, is nothing more that the Word, and wisdom, of God.
The Holy Spirit, as His name indicates, is Holy in virtue of His origin, His spiration; He comes therefore from a holy principle; now holiness resides in the will, as wisdom is in the intellect. Holy Spirit
All this makes me wonder what do the Catholics believe on the Holy Spirit? It is confusing because different Catholics denominations as noted in the article (another oops) hold all sorts of differing opinions on the matter. If you so believe in the Holy Spirit, how do you know that you have Him? Isn't that all part of our faith discussion? Do you believe in the Holy Spirit and does He guide you? How do you know?
Atonement - As far as atonement, get with the times. The blood atonement was sooooooo 15th century. You need to update your theology with the latest thought coming out of the Vatican for the last 500 years. I would suggest reading up on the Atonement
(d) These ideas retained their force well into the Middle Ages. But the appearance of St. Anselm's "Cur Deus Homo?" made a new epoch in the theology of the Atonement. It may be said, indeed, that this book marks an epoch in theological literature and doctrinal development.
A debt to Divine justice has been incurred; and that debt must needs be paid. But man could not make this satisfaction for himself; the debt is something far greater than he can pay; and, moreover, all the service that he can offer to God is already due on other titles. The suggestion that some innocent man, or angel, might possibly pay the debt incurred by sinners is rejected
the views of St. Anselm and Abelard, the two men who in different ways were the fathers of Scholasticism, shaped the course of later medieval theology. The strange notion of the rights of Satan, against which they had both protested, now disappears from the pages of our theologians.
As both Abelard and Bernard remind us, the Atonement is the work of love. It is essentially a sacrifice, the one supreme sacrifice of which the rest were but types and figures. And, as St. Augustine teaches us, the outward rite of Sacrifice is the sacrament, or sacred sign, of the invisible sacrifice of the heart.
Regarding the atonement, I've read St. Anselm's Cur Deus Homo, and you are misunderstanding the line in the New Advent article that you underlined. In the New Advent article on the atonement, by "innocent man", it is referring to a mere man, not the incarnate Christ. That can be seen if you read the end of the sentence (which you failed to include in your quotation). That ending reads: "on the ground that in any case this would put the sinner under obligation to his deliverer, and he would thus become the servant of a mere creature." But Christ is not a mere creature.
The Catholic Church nowhere denies the "blood atonement of Christ". Catholics believe that we are reconciled to God through the blood of Christ.
But how about focusing on one thing at a time? Let's resolve this question of how you know now with certainty that you are elect for glory.
