By degrees, the spirit of Christ will take the place of our spirit – a way of thinking, feeling, judging, loving, willing, doing, and suffering, a mental outlook which is extremely cramped and superficial since it is materially dependent on our physical temperament, on our heredity, on the influence of our surrounding circumstances and on the ideas of our time and locality. It is this spirit which must slowly yield to the spirit of Christ, to His way of looking at things, of judging, feeling, loving, acting, and suffering.
Reginald Garrigou-Lagrange OP (1877–1964)
