Begotten means spawn, sire, or breed, from the father.
I am begotten from my father.

I know the definition of “beget”, and that it is different from “proceed”;
Understanding that there is a difference is probably more important than defining them when it comes to understanding the Trinitarian Nature of God, and the distinction of the Persons/relationships of God, the Father, God, the Son, and God, The Holy Spirit.
Forgive me if I misunderstood.
I was just commenting that in the given explaination of the Holy Spirit, it
seemed to confuse what the Church has always taught: that God the Father, alone, is the source of the Son and the Spirit;
And it
seemed to confuse what the Church has always taught about the perfect Unity of the Trinitarian Nature of God: No one (or two) person(s) of the Trinity acts independently of or in isolation from the others. The action of each is the action of all; the action of all is the action of each. And the divine action is essentially one; and everything that belongs to God the Father – life, love, wisdom, truth, blessedness, holiness, power, purity, joy – belongs equally to the Son and the Holy Spirit;
Whatever the Father wills and acts, the Son and the Holy Spirit at the same time wills and acts.
I liked your Catechism’s quote from St. Gregory of Nazianzus, about the gradual revealing or the “progression” of God’s revelation of His Trinitarian Nature as a “condescension”, as reaching down to man, not overwhelming him with the Fullness of His Nature, Power and Glory; it is yet another mercy shown to draw us freely to Him in love;
Code:
"The Old Testament proclaimed the Father clearly, but the Son more obscurely. The New Testament revealed the Son and gave us a glimpse of the divinity of the Spirit. Now the Spirit dwells among us and grants us a clearer vision of himself. It was not prudent, when the divinity of the Father had not yet been confessed, to proclaim the Son openly and, when the divinity of the Son was not yet admitted, to add the Holy Spirit as an extra burden, to speak somewhat daringly. . . . By advancing and progressing "from glory to glory," the light of the Trinity will shine in ever more brilliant rays."
