Beginning with the sixth (1978) Urantia Foundation printing, the word
"millennium" was misspelled as "millenium".
Original Paragraph:
P632:3, 55:7.4
This settled age continues on and on until every inhabited planet in the system
attains the era of stabilization; and then, when the youngest world -- the last
to achieve light and life -- has experienced such settledness for one millennium
of system time, the entire system enters the stabilized status, and the
individual worlds are ushered into the system epoch of the era of light and
life.
