Here is the excerpts from the Catechism of the Council of Trent more fully in context...
"On this class of persons, however, the Church does not confer this Sacrament hastily: she will have it deferred for a certain time; nor is the delay attended with the same danger as in the case of infants, which we have already mentioned: and should any unforeseen accident deprive adults of baptism, their intention of receiving it, and their repentance for past sins, will avail them to grace and righteousness."
While speaking of adults & baptism, it mentions "the same danger" as in the case of infants, which means "death", and following that very thought the sentence continues, "and should any unforeseen accident deprive adults of baptism". This is speaking of death also, not solely because it directly follows the reference to baptism of infants, but also because it says "deprive". Elsewhere it speaks of "delay", but here is says "deprive adults of baptism". That means the adults never receives baptism. This is death.
My idea of what an "unforeseen accident" is:
1) Dropping dead instantly = no time to desire anything, no time to have repentance of past sins.
2) Dying in your sleep = no time to desire anything, no time to have repentance of past sins.
3) Crossing the street getting killed by a bus = no time to desire anything, no time to have repentance of past sins.
God's idea of what an unforeseen accident is:
1) There is no such thing.
Mat 24:42
Watch ye therefore, because ye know not what hour your Lord will come. - We do not know, but God knows from all eternity when He will come for us.
24:43
But know this ye, that if the goodman of the house knew at what hour the thief would come, he would certainly watch, and would not suffer his house to be broken open. [44] Wherefore be you also ready, because at what hour you know not the Son of man will come.
This is what the Church has always taught - we must be ready to die at any moment - if we are not ready, we get punished.
We are taught that like a thief in the night, Our Lord will come for us. IOW, when we least expect it. To believe in a desire for salvation is to be a fool IMO. I mean, even saints trembled! (see the last sentence below)
I have a suggestion. Memorize
Dies Irae and after understanding this most awesome Lex orandi, see if your lex credendi regarding BOD changes.
We stand accused, guilty before Him.....
What horror must invade the mind
When the approaching Judge shall find
And sift the deeds of all mankind!
Now death and nature
with supriseBehold the trembling sinners rise
To meet the Judge's searching eyes.
For now before the Judge severe
All hidden things must plain appear;
No crime can pass unpunished here.
O what shall I, so guilty plead?
And who for me will intercede?
When even Saints shall comfort need?
