Interesting question. I can only tell you what I think (but i’m no priest so I could be very wrong)
I think that Jesus chooses his friends Himself and that every Christian is predestined for this.
The problem with protestants is that they think they are predestined to go to heaven as soon as they are baptized. After that, no matter how bad they behave, they cannot lose their destiny to go to heaven, so they think. Which means that many protestants who believe they are predestined are actually Esaus as saint montfort would call it, and in the end not predestined.
“The problem with protestants is that they think they are predestined to go to heaven as soon as they are baptized”
I’m sure there may be someone, somewhere who thinks that: but after decades of studying and teaching I have never heard of such a thing.
Do you know what a straw man argument is?
“After that, no matter how bad they behave, they cannot lose their destiny to go to heaven, so they think.”
Hyperbole to make a point
Scripture teaches that real faith inevitably produces a changed life (2 Corinthians 5:17). Salvation includes a transformation of the inner person (Galatians 2:20)
The nature of the Christian is new and different (Romans 6:6).
The unbroken pattern of sin and enmity with God will not continue when a person is born again (1 John 3:9-10).
Those with genuine faith follow Christ (John 10:27),
love their brothers (1 John 3:14),
obey God’s commandments (1 John 2:3; John 15:14),
do the will of God (Matthew 12:50),
abide in God’s Word (John 8:31),
keep God’s Word (John 17:6),
do good works (Ephesians 2:10),
and continue in the faith (Colossians 1:21-23; Hebrews 3:14).
Scripture teaches that behavior is an important test of faith.
Obedience is evidence that one’s faith is real (1 John 2:3).
On the other hand, the person who remains utterly unwilling to obey Christ does not evidence true faith (1 John 2:4)
Scripture teaches that** genuine believers** may stumble and fall, but they will persevere in the faith (1 Corinthians 1:8).
Those who later turn completely away from the Lord show that they were never truly born again (1 John 2:19).
IOW** If your faith didn’t change then you faith didn’t save you**
That is what Sola Sciptura practicing , Sola Fide believing Christians believe
not “they are predestined to go to heaven as soon as they are baptized”"
