Notice how the church says “may” - not “will.” We don’t understand how this works. We have no idea if many people have found salvation this way, or few, or none (just because it’s possible doesn’t mean it’s been done).
This is why the Church never forgets her commission to Baptize the world. Baptism offers assurances - it is 100% effective.
My only addition here is, the following qualifications
All the following warnings Paul gave in his letters, were written to the baptized. They were written to people already “in” the Church . Therefore, Paul is warning, one has to be responsible and obedient to their baptism, and persevere in the faith till the end of this life, or there is no salvation for THEM in the next, even though they are baptized.
Also a few examples from the CCC as well, (all emphasis mine)
Titus 3:10
“As for a man who is factious (
αἱρετικὸν heretic ), after admonishing him once or twice, have nothing more to do with him, 11 knowing that such a person is perverted and sinful; he is self-condemned.”
One could ask what does baptism have to do with one in heresy?
2089"*Heresy *is the obstinate
post-baptismal denial of some truth which must be believed with divine and catholic faith, or it is likewise an obstinate doubt concerning the same;
AND then there are these warnings from Paul. To be in the Church in the first place one has to be baptized
Romans 16:17-20 ,
Galatians 5:19-21 ,
διχοστασίας dichostasia* =*
division / dissension / factions /sedition the same Greek word in both Rom 16:17. And Gal 5:19… If one continues in that sin they “will not inherit heaven*”*
AND there is also (anyone is capable of committing mortal sin baptized or not)
**1861 **Mortal sin is a radical possibility of human freedom, as is love itself. It results in the
loss of charity and the privation of sanctifying grace, that is, of the state of grace. If it is not redeemed by repentance and God’s forgiveness, it causes
exclusion from Christ’s kingdom and the eternal death of hell, for our freedom has the power to make choices for ever, with no turning back. However, although we can judge that an act is in itself a grave offense, we must entrust judgment of persons to the justice and mercy of God.
Even those
837* "*Fully incorporated into the society of the Church are those who, possessing the Spirit of Christ, accept all the means of salvation given to the Church together with her entire organization, and who - by the bonds constituted by the profession of faith, the sacraments, ecclesiastical government, and communion - are joined in the visible structure of the Church of Christ, who rules her through the Supreme Pontiff and the bishops. Even though incorporated into the Church,
one who does not however persevere in charity is not saved. He remains indeed in the bosom of the Church, but ‘in body’
not 'in heart’
In general, as Jesus says regarding love, as in of Him, i.e. charity towards Him and in extension neighbor, and in extension His body the Catholic Church
[Mark 12:30-31](
Mark - John the Baptist Prepares the Way - The - Bible Gateway 12:30-31&version=NRSVCE) ,
John 14:15
How many people THINK they obey what Jesus commands but actually don’t?
The previous passages point towards warnings and consequences against grave offenses to charity, either to God or His body the Church, and remaining in that state. The baptized aren’t exempt from these warnings and consequences.
That’s all I would add.
