The Two Sides of Masonry
And Freemasons wear a lambskin apron which is a mockery to the LORD Jesus Christ, the Son of God, the Lamb of God Who shed His blood, died to pay for our sin and after 3 days, rose from the grave.
If you say you are a Christian and a Freemason, you need to make a choice as you can't be both.
