Reply to Objection 2: For all that a man may return to the laity, the character always remains in him. This is evident from the fact that if he return to the clerical state, he does not receive again the order which he had already.
The Reply to the Third Objection is the same as to the First.
Whether the character of Order presupposes the baptismal character?
Objection 1: It would seem that the character of Order does not presuppose the character of Baptism. For the character of Order makes a man a dispenser of the sacraments; while the character of Baptism makes him a recipient of them. Now active power does not necessarily presuppose passive power, for it can be without it, as in God. Therefore the character of Order does not necessarily presuppose the character of Baptism.
Objection 2: Further, it may happen that a man is not baptized, and yet think with probability that he has been baptized. If therefore such a person present himself for Orders, he will not receive the character of Order, supposing the character of Order to presuppose the character of Baptism; and consequently whatever he does by way of consecration or absolution will be invalid, and the Church will be deceived therein, which is inadmissible.
On the contrary, Baptism is the door of the sacraments. Therefore since Order is a sacrament, it presupposes Baptism.
I answer that, No one can receive what he has not the power to receive. Now the character of Baptism gives a man the power to receive the other sacraments. Wherefore he that has not the baptismal character, can receive no other sacrament; and consequently the character of Order presupposes the character of Baptism.
Reply to Objection 1: In one who has active power of himself, the active does not presuppose the passive power; but in one who has active power from another, passive power, whereby he is enabled to receive the active power, is prerequisite to active power.
Reply to Objection 2: Such a man if he be ordained to the priesthood is not a priest, and he can neither consecrate, nor absolve in the tribunal of Penance. Wherefore according to the canons he must be baptized, and reordained (Extra De Presbyt. non Bapt., cap. Si quis; cap. Veniens). And even though he be raised to the episcopate, those whom he ordains receive not the Order. Yet it may piously be believed that as regards the ultimate effects of the sacraments, the High Priest will supply the defect, and that He would not allow this to be so hidden as to endanger the Church.
Whether the character of Order necessarily presupposes the character of Confirmation?
Objection 1: It would seem that the character of Order necessarily presupposes the character of Confirmation. For in things subordinate to one another, as the middle presupposes the first, so does the last presuppose the middle. Now the character of Confirmation presupposes that of Baptism as being the first. Therefore the character of Order presupposes that of Confirmation as being in the middle.
Objection 2: Further, those who are appointed to confirm should themselves be most firm. Now those who receive the sacrament of Order are appointed to confirm others. Therefore they especially should have received the sacrament of Confirmation.
On the contrary, The apostles received the power of order before the Ascension ( Jn. 20:22 ), where it is said: "Receive the Holy Ghost." But they were confirmed after the Ascension by the coming of the Holy Ghost. Therefore order does not presuppose Confirmation.
I answer that, For the reception of Orders something is prerequisite for the validity of the sacrament, and something as congruous to the sacrament. For the validity of the sacrament it is required that one who presents himself for Orders should be capable of receiving them, and this is competent to him through Baptism; wherefore the baptismal character is prerequisite for the validity of the sacrament, so that the sacrament of Order cannot be conferred without it. On the other hand, as congruous to the sacrament a man is required to have every perfection whereby he becomes adapted to the exercise of Orders, and one of these is that he be confirmed. Wherefore the character of Order presupposes the character of Confirmation as congruous but not as necessary.
Reply to Objection 1: In this case the middle does not stand in the same relation to the last as the first to the middle, because the character of Baptism enables a man to receive the sacrament of Confirmation, whereas the character of Confirmation does not enable a man to receive the sacrament of Order. Hence the comparison fails.
Reply to Objection 2: This argument considers aptness by way of congruity.
Whether the character of one Order necessarily presupposes the character of another Order?
Objection 1: It would seem that the character of one Order necessarily presupposes the character of another Order. For there is more in common between one Order and another, than between Order and another sacrament. But the character of Order presupposes the character of another sacrament, namely Baptism. Much more therefore does the character of one Order presuppose the character of another.
Objection 2: Further, the Orders are degrees of a kind. Now no one can reach a further degree, unless he first mount the previous degree. Therefore no one can receive the character of a subsequent Order unless he has first received the preceding Order.
On the contrary, If anything necessary for a sacrament be omitted in that sacrament, the sacrament must be repeated. But if one receive a subsequent Order, without receiving a preceding Order, he is not reordained, but he receives what was lacking, according to the canonical statutes (cap. Tuae literae, De clerico per salt. prom.). Therefore the preceding Order is not necessary for the following.
I answer that, It is not necessary for the higher Orders that one should have received the minor Orders, because their respective powers are distinct, and one, considered in its essentials, does not require another in the same subject. Hence even in the early Church some were ordained priests without having previously received the lower Orders and yet they could do all that the lower Orders could, because the lower power is comprised in the higher, even as sense in understanding, and dukedom in kingdom. Afterwards, however, it was decided by the legislation of the Church that no one should present himself to the higher orders who had not previously humbled himself in the lower offices. And hence it is that according to the Canons (cap. Tuae literae, De clerico per salt. prom.) those who are ordained without receiving a preceding Order are not reordained, but receive what was lacking to them of the preceding Order.
Reply to Objection 1: Orders have more in common with one another as regards specific likeness, than order has with Baptism. But as regards proportion of power to action, Baptism has more in common with Order, than one Order with another, because Baptism confers on man the passive power to receive Orders, whereas a lower Order does not give him the passive power to receive higher Orders.
Reply to Objection 2: Orders are not degrees combining in one action or in one movement, so that it be necessary to reach the last through the first; but they are like degrees consisting in things of different kinds, such as the degrees between man and angel, and it is not necessary that one who is an angel be first of all a man. Such also are the degrees between the head and all members of the body; nor is it necessary that that which is the head should be previously a foot; and thus it is in the case in point.
