3. From the Council of Trent concerning original sin:

(a) The entire Adam, through the offense of his prevarication, was changed, in body and soul, for the worse. The prevarication of Adam injured not only himself but also his posterity; it transfused not only death and pains of the body into the whole human race but also sin itself, which is the death of the soul (Session 5, numbers 1, 2).

(b) This sin of Adam — which in its origin is one, and being transfused by propagation, not by imitation, is in each one as his or her own — cannot be taken away by any other remedy than the merit of the one and only Savior, our Lord Jesus Christ, who reconciled us to God in his own blood, being made justice, sanctification, and redemption for us (Session 5, number 3).

(c) All human beings had lost their innocence in the prevarication of Adam; they became unclean and by nature children of wrath (Session 6, chapter 1).

86. The goats mentioned in Zechariah have the same meaning:

My wrath blazes against the shepherds, and I will execute judgment upon the goats. (Zechariah 10:3)

Likewise, the goats mentioned in Ezekiel:

Behold, I am judging between one flock animal and another, between rams and goats. Is it too little for you to have eaten up the good pasture? Will you also trample what remains of the food with your feet? You attack all the weak sheep with your horns until you have scattered them. Therefore I will save my flock, so that it will no longer be prey. (Ezekiel 34:17, 18, 21, and following)
