Whether the character of Confirmation presupposes of necessity, the baptismal character?

Objections

Objection 1 : It seems that the character of Confirmation does not presuppose, of necessity, the baptismal character. For the sacrament of Confirmation is ordained to the public confession of the Faith of Christ. But many, even before Baptism, have publicly confessed the Faith of Christ by shedding their blood for the Faith. Therefore the character of Confirmation does not presuppose the baptismal character.
Objection 2 : Further, it is not related of the apostles that they were baptized; especially, since it is written (Jn. 4:2) that Christ "Himself did not baptize, but His disciples." Yet afterwards they were confirmed by the coming of the Holy Ghost. Therefore, in like manner, others can be confirmed before being baptized.
Objection 3 : Further, it is written (Acts 10:44-48) that "while Peter was yet speaking . . . the Holy Ghost fell on all them that heard the word . . . and [Vulg.: 'for'] they heard them speaking with tongues": and afterwards "he commanded them to be baptized." Therefore others with equal reason can be confirmed before being baptized.
