Groups don't get saved, individuals do.
Acts 13:48 *And when the Gentiles heard this, they were glad, and glorified the word of the Lord: and as many as were ordained to eternal life believed.
Individuals in the GROUP are saved, individuals outside the GROUP are lost. Why? Because it was the GROUP God foreknew/prechose/predestined and not the individual.
The context leading up to Acts 13:48 does not support Calvinism.
Acts 13:43 "Now when the congregation was broken up, many of the Jews and religious proselytes followed Paul and Barnabas: who, speaking to them,
persuaded them to continue in the grace of God."
There is no "persuasion" in what God supposedly preordained. Persuasion has to do with the will of men, they must choose of their own will to remain in God's grace for if God preordained who would or would not be in His grace, there is no persuasion for men can only do what God forces man to do.
Acts 13:47 "For so hath the Lord commanded us,
saying, I have set thee to be a light of the Gentiles, that thou shouldest be for
salvation unto the ends of the earth".
"Ends of the earth" is figurative for all nations, every man. So salvation is not just meant for just lucky ones God randomly chosen.

Furthermore:
Acts 13:42 And when the Jews were gone out of the synagogue, the
Gentiles besought that these words might be preached to them the next Sabbath.
Note that is was the Gentiles own free will, own desire of the Gentiles to hear the word of God preach and it was this free will and desire that lead them to hear Paul preach and be saved.
Acts 13:46 Then Paul and Barnabas waxed bold, and said, It was necessary that the word of God should first have been spoken to you:
but seeing ye put it from you, and judge yourselves unworthy of everlasting life, lo, we turn to the Gentiles.
So in the context, Luke is contrasting the Jews who of their own free will choice put God's word away from themselves to the Gentiles free will choice in wanting to hear Gods word. In verse 48, the underlying Greek word "tasso" the KJV uses "ordained". It really means to set in order, set in place, to determine. So verse 48 is saying as many Gentiles that were set in order by what they heard Paul preach about eternal life believed. I see the KJV had a Calvinistic bias in how it 'translated" verse 48.
So Luke is showing the contrast when God sent his word to the Jews who set/determined themselves to reject it contrasted to the Gentiles who determined/set themselves to hear and receive it. It cannot be argued the Gentiles belief was predetermined by God when the Jews unbelief and rejection of GOd's word was their own choice.
Point being, the context shows that God did NOT ordain the Jews to not receive His word no more than God ordained certain Gentiles to hear and accept His word.
Here are what some with a Calvinistic bias have to say about verse 48, (my emp)
AT Robertson:
As many as were ordained to eternal life (
osoi hsan tetagmenoi eiv zwhn aiwnion). Periphrastic past perfect passive indicative of
tassw, a military term to place in orderly arrangement. The word "ordain" is not the best translation here. "Appointed," as Hackett shows, is better. The Jews here had voluntarily rejected the word of God. On the other side were those Gentiles who gladly accepted what the Jews had rejected, not all the Gentiles. Why these Gentiles here ranged themselves on God's side as opposed to the Jews Luke does not tell us.
This verse does not solve the vexed problem of divine sovereignty and human free agency. There is no evidence that Luke had in mind an absolutum decretum of personal salvation. Paul had shown that God's plan extended to and included Gentiles. Certainly the Spirit of God does move upon the human heart to which some respond, as here, while others push him away.
