Laudator Temporis Acti

Tertullian, On the Soul 1.6 (tr. Edwin A. Quain):

Learn from God about that which you have received from God; if you don't learn it from God, you never will from anyone else. For, who can reveal what God has concealed? Whom would we ask? If we are ignorant, let us be content. It is safer and better to be ignorant, if God has not revealed it, than to know something which human presumption has discovered.

a deo discat quod a deo habeat, aut nec ab alio, si nec a deo. quis enim revelabit quod deus texit? unde sciscitandum est? unde et ignorare tutissimum est. praestat per deum nescire, quia non revelaverit, quam per hominem scire, quia ipse praesumpserit.

Id. 2.7:

The Christian, however, can plumb the depths of this topic with the aid of a few simple words. Things that are absolutely certain are always simply explained and his investigations should go no further than we are permitted. The Apostle has forbidden us to indulge in endless questions. We can learn no more about the soul than God has revealed and His revelation is the sum and substance of the whole matter.

Christiano autem paucis ad scientiam huius rei opus est. nam et certa semper in paucis, et amplius illi quaerere non licet quam quod inveniri licet; infinitas enim quaestiones apostolus prohibet. porro non amplius inveniri licet quam quod a deo discitur; quod autem a deo discitur, totum est.
