Context

“By the way of generation and movement we must of necessity come to the imperfect before the perfect. And therefore Christ was made known first through other creatures, and afterwards He Himself manifested Himself perfectly. Reply Obj. 2: Although hidden wisdom is useless, yet there is no need for a wise man to make himself known at all times, but at a suitable time; for it is written (Ecclus. 20:6) : "There is one that holdeth his peace because he knoweth not what to say: and there is another that holdeth his peace, knowing the proper time." Hence the wisdom given to Christ was not useless, because at a suitable time He manifested Himself.” source
