Aquinas is worth reading. He has stood the test of time. And even where he errs, you can learn more from the errors of a great mind than you can learn from the truths of a small mind. You can see a whole lot farther standing on the shoulders of giants.
Only Jesus has prophecies made hundreds of years in advance made literally true. Only He did miracles; only His immediate followers claimed He died and rose from the dead, so in comparison, He comes out superior to other great religious leaders.
