Kochuthara, CMI, in his excellent study, The Concept of Sexual Pleasure, offers this summary of the paradigm shift:
When we consider the theological developments from the second half of the 20th century, we can identify a notable change in the emphasis on procreation. The emphasis is no more on procreation, but on love. Mutual love and union of the couple is the most important purpose of marriage as well as that of the marital union. We may understand the difference only when we consider that tradition up to modern times, which practically assigned no place to the discussion on love as pertaining to conjugal life. Besides considering love as a necessary condition for conjugal intimacy, all other aspects of conjugal life, including the procreative dimension, are given their significance based on the criterion of love (463).
