The Bible proclaims that Christ is Lord. He reigns with God the Father even today over the entire universe (Eph. 1:20-22). Those who trust in Christ for salvation also acknowledge him as Lord: "if you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved" (Rom. 10:9). If he is the Lord, we are his servants. What does that imply about how we look at ourselves and at the world around us and at the things that we study?
Since Christ rules over all, we have to acknowledge his Lordship in every aspect of our lives. There is no part that we can cordon off and keep to ourselves privately. This universal Lordship extends to our thoughts. The Apostle Paul saw the implications when he talked about taking "every thought captive to obey Christ" (2 Cor. 10:5). Every academic discipline, every department of every university in the world, should look different, because Christ and his wisdom (1 Cor. 1:30; Col. 2:3) needs to be acknowledged.
How does this work out in practice, in discipline after discipline? That is a long story. It is still in progress, because Christians are gradually learning to think God's thoughts after him, on a creaturely level, and to submit every thought to him in every discipline.
