Words to open a Masonic lodge meeting:

“As the sun rises in the EAST, to open and govern the day, so rises the worshipful master in the EAST to open and govern the lodge, set the craft to work and give them proper instructions.”  George Oliver

The Book of Moses refers to the Dispensation of Jesus Christ as the “meridian of time”. This is a Masonic reference to the midpoint in a day, high noon, when the sun is at the top of the earth’s circle of rotation.

References in LDS scripture:

“…even him whom he declared should come in the meridian of time, who was prepared from before the foundation of the world.” (Moses 5:57) 

“…the Son of Man, even Jesus Christ, a righteous Judge, who shall come in the meridian of time.” (Moses 6:57)

“…through the blood of mine Only Begotten, who shall come in the meridian of time.”  (Moses 6:62)

“And the Lord said: It shall be in the meridian of time, in the days of wickedness and vengeance.” (Moses 7:46)

“…after he came in the meridian of time…” (D&C, 20:26) – attributed to Phelps

“The same which came in the meridian of time unto mine own, and mine own received me not;” (D&C, 39:3) – attributed to Smith  

Masonry makes reference to the meridian line in the Masonic lodge and its significance with respect to the movement of the Sun:

“The sun in the South is represented in Freemasonry by the Junior Warden, for this reason: when the sun has arrived at the zenith, at which time he is in the South, the splendor of his beams entitles him to the appellation which he receives in the instructions as “the beauty and glory of the day.” Hence, as the Pillar of Beauty which supports the Lodge is referred to the Junior Wardens that officer is said to represent “the sun in the South at High Twelve,” at which hour the Craft are called by him to refreshment, and therefore is he also placed in the South that he may the better observe the time and mark the progress of the shadow over the dialplate as it crosses the meridian line.”  Mackey’s Encyclopedia of Freemasonry
