How did Thomas Aquinas attempt to explain the differences between Aristotle and the Church's teachings?

Answer 1

"One of the arguments put forth by Aquinas is called the First Cause argument: every effect has a cause, the universe is an effect, therefore the universe has a cause, and that cause is God. For Aquinas, God alone didn't have a beginning. Therefore, for Aquinas, the question what caused God was not relevant. And Aquinas' idea of cause was not complicated as it would be in the 20th century with the arrival of quantum physics."

Answer 2

Thomas Aquinas sought to reconcile Aristotle's philosophy with the teachings of the Church by integrating reason and faith. He believed that reason could lead to an understanding of God's truths, and that philosophical principles could complement theological doctrines. Aquinas argued that where Aristotle's teachings conflicted with Christian doctrine, it was due to Aristotle's limitations in understanding divine mysteries rather than any inherent contradiction between reason and faith.
