“The Egyptian hierophant was given a square head-dress, which he had to wear always, and a square without which, he could never go abroad. The perfect Tau formed of the perpendicular (descending male ray or spirit), a horizontal line (or matter, female ray), and the mundane circle was an attribute of Isis, and it is but at his death that the Egyptian cross was laid on the breast of his mummy. These therefore fallible – there is no institution that has done so much and is yet capable of square hats are worn unto this day by the Armenian priests. The claim that the cross is purely a Christian symbol introduced after our era, is strange indeed, when we find Ezekiel stamping the foreheads of the men of Judah, who feared the Lord (Ezekiel 9:4), with the signa Thau, as it is translated in the Vulgate.
In the ancient Hebrew this sign was formed 
, but in the original Egyptian hieroglyphics as a perfect Christian cross 
. In the Revelation, also, the “Alpha and Omega” (spirit and matter), the first and the last, stamps the name of his Father on the foreheads of the elect.
And if our statements are wrong, if Jesus was not an initiate, a Master-Builder, or Master-Mason as it is now called, how comes it, that on the most ancient cathedrals we find his figure with Mason’s marks about his person? In the Cathedral of Santa Croce, Florence, over the main portal can be seen the figure of Christ holding a perfect square in his hand.
The surviving “Master-Builders” of the operative craft of the true Temple, may go literally half-naked and wander slipshod forever – now not for the sake of puerile ceremony, but because, like the “Son of man”, they have not where to lay their heads – and yet be the only surviving possessors of the “Word”. Their “cable-tow” is the sacred triple cord of certain Brahman-Sannyasi, or the string on which certain lamas hang their yu-stone; but with these apparently valueless talismans, not one of them would part for all the wealth of Solomon and Sheba. The seven-knotted bamboo stick of the fakir can become as powerful as the rod of Moses, “which was created between the evenings, and on which was engraven and set forth the great and glorious NAME, with which he was to do the wonders of Mizraim.”
But these “operative workmen” have no fear that their secrets will be disclosed by treacherous ex-high priests of chapters, though their generation may have received them through others than “Moses, Solomon, and Zerubbabel.” Had Moses Michael Hayes, the Israelite Brother who introduced Royal Arch Masonry into this country (in December 1778), had a prophetic presentment of future treasons, he might have instituted more efficacious obligations than he has.”
