Most people who allow "inclusiveness", do so by somehow diminishing or downplaying the Bible's teaching on exclusivity (or "the scandal of particularity"), or by denying the Bible's inerrancy or truthfulness altogether.
But I've found another view, that not only maintains the Bible's truthfulness, but in the process also explains a lot we see in the world, in light of the Bible's claims, that leads most to reject it altogether.
It starts from eschatology. Most mainstream Christians holding the exclusive view, hold to some form of
futurism. God's work is not finished; he still has to return and end death, and then all sin and judgment will be abolished. In the meantime, we are all "running the race" as Paul says, and thus have to excercise "faith" in Christ alone, and improved behavior (as they were, duties) in order to go from "lost" to "saved".
However, whatever this coming "fulfillment" they were "running" to, was said to be something
in their lifetimes,
NOT thousands of years later. Christ had even said "
some of you standing here shall not taste death until the Son of Man comes".
The eschatology known as
Preterism holds that this was the the destruction of the Temple, in AD70, when some of those people were in fact still living. That ended the system of Law that condemned man and required a "response" from him to be saved in the first place. Hence, the Kingdom, of salvation, spreads to all unconditionally, just like the mustard seed growing into a big plant.
The problem arose, because many Christians did not recognize this in AD70, and continued to look for a return of Christ, which they then called "delayed".
The Church is at the same time becoming corrupted with pagan doctrines, philosophies and practices from the Greek world around them. (antisemitism, ritualism, flesh is bad, only "spirit" is good, etc). They begin organizing the visible church into a powerful institution to the point that Constantine recognized them as the state religion, ending persecution, and yet making them powerful enough to become persecutors. And hence, the whole dark ages of the church. When not using the sword, fear of Hell was also good to keep people in line and maintain the power. Eventually cracks begin to form, and people rebel against the corruption, and form an increasing number of schisms or denominations. All of them denouncing each other, and yet nearly all claiming to represent "the truth". Almost all agreed on the necessity of "duty faith" to be saved, despite all of the people they see in the world and church that has turned them against faith.
Hence, the Christianity we all grew up with, and many of whom rejected. Even most preterists today, while still holding the AD70 concept, hold on to hell for all unbelievers. So the branch of preterism that teaches grace has spread to all unconditionally, is known generically as "
Pantelism". Here is a site that articulates on this (and links to other articles).
Comprehensive Grace - Tim King
I like the way he speaks of "the covenantal framework of biblical eschatology" that sets pantelism apart from regular universalism, which is just unbiblically pluralistic. So hence, "salvation is found in no other"?"No one comes to the Father but by [Christ]" is still true. Salvation is in or because of Christ, not other gods, and not worship of other gods being accepted as "other paths" to the true God, and all that stuff. However, salvation being by Christ alone does not necessarily require any "response" on those saved. The widespread belief that it did was based on pairing "Salvation in no other"/"No one comes to the Father but by me" with verses like the familiar Acts 16:31 "Believe on the Lord Jesus Christ and you shall be saved", and several statements by Jesus in the Gospels, especially John. But that was all spoken to those in that age, and the age ended about 40 years later. It does not necessarily carry over to everyone after that, especially when that age of spiritual death was said to end soon.
