33 But it will not do to possess these facts and truths after the fashion of an abstract memory lesson or lifeless commentary. They must lead to practical results. They must impel us to subject our senses and their faculties to reason, as illuminated by the Catholic faith. They must help to cleanse and purify the heart, uniting it to Christ more intimately every day, growing ever more to His likeness, and drawing from Him the divine inspiration and strength of which it stands in need. They must serve as increasingly effective incentives to action: urging men to produce good fruit, to perform their individual duties faithfully, to give themselves eagerly to the regular practice of their religion and the energetic exercise of virtue. "You are Christ's, and Christ is God's." Let everything, therefore, have its proper place and arrangement; let everything be "theocentric," so to speak, if we really wish to direct everything to the glory of God through the life and power which flow from the divine Head into our hearts: "Having therefore, brethren, a confidence in the entering into the holies by the blood of Christ, a new and living way which He both dedicated for us through the veil, that is to say, His flesh, and a high priest over the house of God; let us draw near with a true heart, in fullness of faith, having our hearts sprinkled from an evil conscience and our bodies washed with clean water, let us hold fast the confession of our hope without wavering . . . and let us consider one another, to provoke unto charity and to good works."
