Go deeper. Cite the source.

TheoTank Research gives you citation-grounded access to primary theological texts. Ask a question, get an answer with inline citations to specific passages — in the original Latin, Greek, or vernacular, with English alongside.

This isn't synthesis. It's direct engagement with a theologian's own corpus.

"Whether God exists?"

Aquinas argues from five ways that the existence of God can be demonstrated. The third way — from possibility and necessity — concludes that there must be a being having of itself its own necessity, not receiving it from another.

¹ Summa Theologiae I, q.2, a.3

"Ergo est necesse ponere aliquam causam efficientem primam: et hanc omnes dicunt Deum."

"Therefore it is necessary to posit some first efficient cause, and this everyone calls God."
