"Nor even imply?"
Here:
On adults, however, the Church has not been accustomed to confer the Sacrament of Baptism at once, but has ordained that it be deferred for a certain time. The delay is not attended with the same danger as in the case of infants, which we have already mentioned; should any unforeseen accident make it impossible for adults to be washed in the salutary waters, their intention and determination to receive Baptism and their repentance for past sins, will avail them to grace and righteousness.
It certainly at least implies - to put it midly - that one can be saved by a desire for baptism with repentance. If "it is impossible for adults to be washed in the salutary waters," that desire and repentance will "avail them to grace and righteousness."
And what is the "danger as in the case of infants"?
Here:
Ok, the RC first off states there is no danger of death involved, if there were, then the adult must be be baptized asap like infants who are more prone shall we say, to die at any time. This is why for adults there is a delay, but not for infants. However, when there is a danger of death, read the very next chapter, do that and you will see the RC teaches that:
In Case Of Necessity Adults May Be: Baptised At Once
Sometimes, however, when there exists a just and necessary cause, as in the case of imminent danger of death,
Baptism is not to be deferred, particularly if the person to be baptised is well instructed in the mysteries of faith.
This we find to have been done by Philip, and by the Prince of the Apostles, when without any delay, the one
baptised the eunuch of Queen Candace; the other, Cornelius, as soon as they expressed a wish to embrace the
faith.
To continue with the first part where it says:
"should any unforeseen accident make it impossible for adults to be washed in the salutary waters, their intention and determination to receive Baptism and their repentance for past sins, will avail them to grace and righteousness."
Grace and righteousness are attributes of the living, not the dead. Neither Trent nor the RC are talking about the attainment of salvation, which is an attribute of the dead, not the living.
So yes, their intention etc. "
will avail", which is to say will help, or aid them, and be of use toward grace and righteousness, which is justification, but it does not reward or even give them grace or righteousness, nor does it mean it will reward them salvation.
So your concern of being opposed to the RC really has no basis.
