“If Masonry were really purveying pure truth, as it claims, then why would it need to keep its ancient secrets hidden? For, as Jesus said in John 18:20, “I have always taught in synagogues and in the temple, where all Jews come together; I have said nothing secretly.” In reality, there are two reasons for Masonic secrecy.
First of all, if every Mason’s wife knew the exact content of the “blood oaths” to which her husband had sworn, then Masonry would collapse in a single night. In the wider scope, anti-Masonic investigations, inquisitions, and purges have been launched whenever the order’s secrets have been revealed. Secondly, secrecy makes members feel that they are part of an elite group. This tends to better weld them into a unit.”
