Masonry does not teach any path to salvation. That is the job of a church, not a fraternity. The closest Masonry comes to this issue is to point to the open Bible and tell the Mason to search there for the path to eternal life. Masonry believes in the importance of doing good works, but as a matter of gratitude to God for His many great gifts and as a matter of individual moral and social responsibility. The path to salvation is found in each Mason's house of worship, not in his lodge.
Universalism is the doctrine that all men and women are ultimately saved.
Masonry does not teach universalism nor any other doctrine of salvation. Again, doctrines of salvation are the province of a church, not a fraternity. It's important to remember that any Masonic author writes for himself alone, not as an official of the Masonic Fraternity. Masonry simply does not have a position, official or otherwise, on salvation. Since men of all faiths are welcome in Freemasonry, Masons are careful not to offend the faith of any.
