Freemasonry is a journey – both spiritually and actually. When you are initiated you become an Entered Apprentice, this is the first degree of Freemasonry. After learning a little more about the craft you may be passed to the second degree and be known as a Fellow Craft Freemason.
After a little more time and learning, you will (hopefully) be raised to the third degree and can call yourself a Master Mason.
As well as the three degrees of Freemasonry, there are various roles within the Lodge and you will be asked to take on one of these when the time is right and a position becomes available. These roles also have a hierarchy so you would most likely start with the most junior position and then move up in stages over time.
Each role has a part to play in the ceremonies so you will feel involved from the beginning.
