I posted a catechism saying all that is needed is perfect contrition and that alone suffices, and it suffices even when the recipient never even heard of the existence of the sacrament of baptism. This contradicts "the 3 things." BTW, that scan was posted years ago here on CI by a BODer to defend the idea that the Church teaches a BOD.
You said that "In order to be saved, as a Catholic, you need 3 things : faith, sacraments OR desire for them, and good works." You say this is taught in catechisms and revelation, yet clearly it goes against Scripture so it cannot be found in revelation, and it is contrary to Trent's catechism. I could be wrong, but I maintain there is no such Church teaching on those "3 things."
Please note that while the PPX catechism is directly attributed to Pius X (hence its common name), its composition was entrusted to four theologians, including two archbishops and one bishop under the supervision of three cardinals. I don't know their names, but the pope himself did not write the whole catechism, there were "other fingers in the pie."
There are also valid arguments against what that catechism says regarding a BOD.
It seems that I misread what you wrote and that in my haste to answer I was sloppy.
I meant that I read about BOD/BOB in the Catechism. For the 3 things I mentionned that are necessary for salvation, they do not directly come from the Catechism, but as a logical consequence.
a)Having the faith. Obviously, if someone was baptised but they profess heresies like arianism, they go to hell. This is pretty logical.
b)Having good works.
From Scripture, Matthew 7:15 :
Beware of false prophets, who come to you in the clothing of sheep, but inwardly they are ravening wolves.By their fruits you shall know them. Do men gather grapes of thorns, or figs of thistles? Even so every good tree bringeth forth good fruit, and the evil tree bringeth forth evil fruit. A good tree cannot bring forth evil fruit, neither can an evil tree bring forth good fruit.
If someone has the Catholic faith, as a logical consequence, they will have good works.
Moreover, having good works is an obligation, again from Scripture (Parable of talents):
14 For even as a man going into a far country, called his servants, and delivered to them his goods;
15 And to one he gave five talents, and to another two, and to another one, to every one according to his proper ability: and immediately he took his journey.
16 And he that had received the five talents, went his way, and traded with the same, and gained other five.
17 And in like manner he that had received the two, gained other two.
18 But he that had received the one, going his way digged into the earth, and hid his lord's money.
19 But after a long time the lord of those servants came, and reckoned with them.
20 And he that had received the five talents coming, brought other five talents, saying: Lord, thou didst deliver to me five talents, behold I have gained other five over and above.
21 His lord said to him: Well done, good and faithful servant, because thou hast been faithful over a few things, I will place thee over many things: enter thou into the joy of thy lord.
22 And he also that had received the two talents came and said: Lord, thou deliveredst two talents to me: behold I have gained other two.
23 His lord said to him: Well done, good and faithful servant: because thou hast been faithful over a few things, I will place thee over many things: enter thou into the joy of thy lord.
24 But he that had received the one talent, came and said: Lord, I know that thou art a hard man; thou reapest where thou hast not sown, and gatherest where thou hast not strewed.
25 And being afraid I went and hid thy talent in the earth: behold here thou hast that which is thine.
26 And his lord answering, said to him: Wicked and slothful servant, thou knewest that I reap where I sow not, and gather where I have not strewed:
27 Thou oughtest therefore to have committed my money to the bankers, and at my coming I should have received my own with usury.
28 Take ye away therefore the talent from him, and give it to him that hath ten talents.
29 For to every one that hath shall be given, and he shall abound: but from him that hath not, that also which he seemeth to have shall be taken away.
30 And the unprofitable servant cast ye out into the exterior darkness. There shall be weeping and gnashing of teeth.
c)Sacraments, or a desire for sacraments.
For any people who are able to assist to the Mass, they are obligated to do so. All the obligations regarding sacraments are conditional on being able. Those who are unable do not sin by not doing them. However, they must have a desire to have those sacraments if they could.
All of those facts are extremely, extremely basic. I am not saying anything groundbreaking, anyone who studied the subject would know.
It is also obvious that, if one is not even aware they have obligations, aside from the obligations that come from the natural law inscribed in every human, what can they be expected to do?
2)It doesn't matter if St Pius X wrote the "Catechism of St Pius X" himself or not. If he read it and approved, he is infallible and would certainly not let anyone teach error.
