Both Apostles and Doctors of the Church lived in their own times.  In Aquinas' time---people did not know that the sun was the center of our solar system, that the world was round, that there was a Western hemisphere.  

Sorry, but we are no longer in the Iron Age!  Both Paul and Aquinas came from that time period.  Amazing that Traddies are using a computer, use smart phones drive cars, live in modern homes, everything else modern---and they think that the Church doesn't/can't up-date its understanding of Biblical studies, Spirituality, and Theology.  They never heard of Pius XII's documents such as: 'Mediator Dei' -1947---laity are true participants in the Mass, or 'Humani Generis'-1950---Catholic theologians are to use modern scholarship in their research and 'Divino Afflante Spiritu'--1943--Biblical scholar were to use modern methods of criticism in researching and studying the Bible. 

The church is not/should not be opposed to GROWING and RESPONDING to the needs of God's People.
