Hi Zade,
Welcome to the forum!
I think you have a valid question, in that it does seem like Romans is referring to the "many called".
Perhaps the key is in the original words used. In Romans, the word used in "them he also called" is defined by Thayer as follows:
[u]kaleō[/u]
1) to call
1a) to call aloud, utter in a loud voice
1b) to invite
2) to call, i.e. to name, by name
2a) to give a name to
2a1) to receive the name of, receive as a name
2a2) to give some name to one, call his name
2b) to be called, i.e. to bear a name or title (among men)
2c) to salute one by name
By using E-sword, I found out that there are different words used in Mathew 22:14
For many are called, but few are chosen."
Matthew 22:14
Here the word for called is:
klētos
1) called, invited (to a banquet)
1a) invited (by God in the proclamation of the Gospel) to obtain eternal salvation in the kingdom through Christ
1b) called to (the discharge of) some office
1b1) divinely selected and appointed
And for chosen:
eklektos
1) picked out, chosen
1a) chosen by God
1a1) to obtain salvation through Christ
1a1a) Christians are called “chosen or elect” of God
1a2) the Messiah in called “elect”, as appointed by God to the most exalted office conceivable
1a3) choice, select, i.e. the best of its kind or class, excellence preeminent: applied to certain individual Christians
So although Thayer seems to think the called and the chosen are the same, he nonetheless notes some key differences which are helpful to us. The chosen are indeed "the best of their kind".
Now, keep in mind, the Chosen (Elect) are "called out" of the Called.
So to me, Romans is still speaking of the Elect who were "called" (called by name...since God knows the name of his Chosen, it makes sense that he would spiritually call them by name within their spirits....)
This is not the same meaning as "the many called" in Matthew, who are "invited to the banquet" but not specially and specifically called by name, as the Elect are.
Hope that made sense....
Gotta run.
Peace and God bless us and give us wisdom,
Diana
