在天主愛德開展的脈絡當中，世界格局已經由世俗化轉向後世俗化的社會，不合時宜的世俗社會正義觀點也必然過渡到後世俗化的社會正義觀。首先，筆者將透過天主教的社會訓導彙編，闡明天主教教會關於社會正義理念的構思。其次，筆者將進一步證成，世俗的社會正義是一種愛的匱乏與關係斷裂的價值理念，因此在後形上學思想的時代潮流中，世俗化的社會正義必然轉化為後世俗化的社會正義。最後，筆者立基於愛德的關係存有學角度告別世俗化的社會正義觀點，宣稱宗教在後世俗化社會之中的角色與功能，便是愛德關係存有學的如實開顯與坦露。因此在筆者看來，所謂後世俗化的社會正義就是對匱乏的愛給予關注、輔助與修補，使其得以重構愛的關係網絡，重新連結愛的源頭。

In the unfolding context of Christian Charity, the world pattern has changed from the secular to the post-secular society, and the anachronistic view of secular social justice is bound to transition to a post-secularized perspective of social justice. In the first part of this article, the author will mainly clarify the idea conception of social justice of the Catholic Church through the Compendium of Catholic Social Teaching. Secondly, the author will further justify that the secularized social justice is a lacking value idea of Christian love and relational being. Therefore, in the trend of post-metaphysical thought, secularized social justice must be transformed into post-secularized social justice. Finally, the author will reject the secularized view of social justice from the relational ontological perspective of Christian Charity, and claim that the role and function of religion in a post-secularized society is the revelation and disclosure of relational ontology of Christian Charity. Therefore, in the author´s opinion, the post-secularized social justice is to pay attention to subsidize and reconstruct the relationship network of Christian love, so that we can reconnect the source of Divine love.
