In the context of Freemasonry, "EA" refers to the "Entered Apprentice" degree. This is the first degree in Freemasonry, where the initiate is taught fundamental principles such as the necessity of a belief in God, charity towards all mankind, and the importance of brotherly love. The Entered Apprentice is charged with various moral and ethical responsibilities, including reverence before God and adherence to the Golden Rule.
As noted by Carl H. Claudy in his work, "In the Entered Apprentice's Degree the initiate is taught the necessity of a belief in God; of charity toward all mankind, 'more especially a brother Mason'; of secrecy; the meaning of brotherly love; the reasons for relief; the greatness of truth; the advantages of temperance; the value of fortitude; the part played in Masonic life by prudence, and the equality of strict justice."
