Is there a standard term within theological literature for the set of people who will receive eternal life?
I've noticed that many Christians use the word "Christians" to refer to this set of people, but that's either deliberate shorthand or confused thinking. For example, Christians believe that pre-Messianic Jews will also receive eternal life. Christians who believe in an age of accountability believe that infants receive eternal life, and Universalists believe that all people will receive eternal life.
I hope it's clear that what I'm asking about here is the name of the set, not its contents. Discussions about Universalism, the age of accountability, and other soteriological or eschatological topics would be much easier if this concept had a standard name, so I'm surprised I haven't encountered one.
The closest thing I've seen comes from Paul's writings. He refers to this group of people many times throughout the Epistles, and when he does, it's typically translated as "the elect". However, as far as I'm aware, modern theologians rarely use this term outside of debates about Calvinism.
