SEC'ULAR, a. [L. secularis, from seculum, the world or an age.]
1. Pertaining to the present world, or to things not spiritual or holy; relating to things not immediately or primarily respecting the soul, but the body; worldly. The secular concerns of life respect making making provision for the support of life, the preservation of health, the temporal prosperity of men, of states, &c.
