Read A Masonic Bible Online
Read the King James version of the Bible (see link in Resources). This version of the Bible is the one most commonly used by the Masons.
Review the Bible verses closely associated with the Masonic degrees (see link in Resources).
Look at "Morals and Dogma" by Albert Pike (see link in Resources). Though for many years this text has been called "The Bible of Freemasonry," it hasn't been used since 1974. Most modern-day Masons have never heard of it.
