This is the canon as shown in
The Catholic Encyclopedia, on the New Advent website. This translation is a little better than the “old English version” that most people here have been using, because it’s from a more modern time period. (I think it’s from the early 20th century.) All of the canons in this particular section concern erroneous beliefs regarding Baptism, that were causing doubts or conflicts about the Church’s teachings.
This is the main proposal in question, which begins with, “
If anyone says:”
“
Those baptized as infants are to be asked when they have grown up, whether they wish to ratify what their sponsors had promised for them at their baptism,”
This proposal is found to be heretical because it questions the efficacy of Infant Baptism, by suggesting that something else needs to be done to confirm that its still valid in adults. The Church is affirming that any Baptism performed by the Church, or by anyone using the proper formula, is valid forever. It cannot be “undone”, or “redone”. Nor does anyone have to justify their Baptism to anyone that might question them when they “grow up”. The Church gives special instruction to the parents, and to the sponsors, before Baptizing any infant, that
they are responsible for teaching the Faith to the child as it gets older.
Sponsors
"When infants are solemnly baptized, persons assist at the ceremony to make profession of the faith in the child’s name. This practice comes from antiquity and is witnessed to by Tertullian, St. Basil, St. Augustine, and others. Such persons are designated
sponsores, offerentes, susceptores, fidejussores, and
patrini. The English term is godfather and godmother, or in Anglo-Saxon, gossip.
These sponsors, in default of the child’s parents, are obliged to instruct it concerning faith and morals."This is what eliminates any need to ask someone to ‘ratify’ those vows. It’s up to the parents and godparents to do what they promised the Church to do, which is to instruct them in the Faith of the Church. When they grow up, it’s their own responsibility and choice as to whether they’ll follow them, or not. But, those vows are always valid in the eyes of God.
Then, we get to the second part:
"
and if they reply that they do not wish to do so, they are to be left to their own will in the matter and not to be forced by penalties to lead a Christian life, except to be deprived of the reception of the Eucharist and of the other sacraments, until they reform."and it ends with, “
Let him be anathema.”
IMHO, this second part of the canon is conditional on the first part, because if we cannot ‘question’ someone’s Baptismal vows, then the second half is already nullified. I now believe that it was included because it ties in with what Erasmus taught, therefore the Council wanted to kill two birds with one canon (pun intended) in case there was any doubt as to whether that part was included or not. But, since so many people here are insisting that there had to be another reason for it to be included, then I suppose I could offer something in the way of an explanation, even though I really don’t think it’s necessary.
First of all, the Church is a society of believers that has a hierarchical structure to govern it. As such, it has full authority to require its membership to follow a certain system of rules, just like any other public association or church has their own rules that they require to be followed by their members. The Church may have been adding the emphasis that she reserves the right to deal with any infraction of those rules as she sees fit, according to her own laws (subject to any civil laws that may apply). She does not give her authority to any individual member, outside of those that receive it through the sacrament of Holy Orders. But, even they have a higher authority over them. This canon might be clarifying her position on that point.
We also have to remember that the Church’s main responsibility (given to her by Jesus Christ) is to safeguard the salvation of the souls of her members. That’s why she has to take things like this so seriously.
