Why do you have any funny secrets at all?

In your daily life you have secrets; your bank cannot disclose your tax file number; your doctor is not allowed to disclose your medical records; you do not disclose your PIN numbers. Being discreet about certain aspects of your personal business is obviously quite normal. Everyone is familiar with the phrase: 'Can you be trusted to keep a secret?'. Therefore, Masons use 'secrets' to test and prove the good character of those who choose to join. This is because to become a Mason requires a person to continually observe, with total sincerity, our high ideals of Integrity, Goodwill and Charity.
