I heard somewhere that Universal Salvation is a heresy. Introduced by Protestantism to support their Solas. Could anybody elucidate?
We do not accept “universal salvation” in any manner. Extremely liberal Protestants (UCC, for example) do to some extent. Universalism is a direct violation of sola fide, sola gratia and most especially, solus Christus. If they’d added universalism, Protestantism wouldn’t have been successful in the first place after the Reformation.
Universalism was popularized by Christian Unitarians, most of whom later split apart and became the Unitarian Universalists and similar names… Modern Unitarians usually identify as Socinians or Biblical Unitarians.
Interestingly, this is a pro-universalism source written by Christians. There’s some oft-cited information in here. The Church Fathers were actually very diverse in their writings, but both common and heterodox (like universalism) sources claim that they all leaned one way or another:
The church fathers closest to the beginning of Christianity and who were well versed in Greek (the language of the New Testament) largely did not believe in endless, torment for the sake of retribution. They believed in limited, corrective punishment based on their understanding of several key Greek words that have been mistranslated.
And, as they always do, blame St. Augustine!!! [Source for both quotes]](“http://www.thebeautifulheresy.com/2005/08/early-church.html”)
Augustine, the first church father to really promote ET to the exlusion of other beliefs, hated Greek and studied mostly in Latin. When the power of the church shifted from the Greek fathers (Alexandrian) to the Latin, the teachings became largely corrupted.
So please don’t pin this off on the Reformers. We wouldn’t even have three out of five solas if they actually believed that “all men, even the most recalcitrant sinner, will be saved” (paraphrasing Tertullian). Luther even tried to reasonably limit the scope of the elect compared to Erasmus (sections 1-3, incl. intro, On the Bondage of the Will).
