In one way it is. It tells us clearly that Christ established a definite Church which He commissioned to teach all nations. It is very simple from this point of view, for men have but to accept the Catholic Church, and be taught by that Church. But the Gospel is not simplicity itself in the way you intend. Men have devoted their lives to the study of the Gospels, preparing themselves for the task by profound research in the Hebrew, Syrian, Arabic, Greek, and Latin languages. And even then, many passages are most difficult to understand.
