Christian apologetics has recently gained a new impetus from authors such as Alister McGrath, who advocates a new, Trinitarian approach to natural theology, the main purpose of which is to confirm a resonance between scientific discoveries and Christian doctrine, thus confirming its credibility. In this article, we use Trinitarian natural theology, which has many advantages over classical natural theology, on the example of the surprising phenomenon of true love. This is manifested in the material world in The Principle of Insufficient Reason, observable through observations of deeds of love, which lack reciprocity and, in the lifeworld in the essence of ratio-sui or selfexplicability of true love, experienceable through experiences of explanation of the reasons for love with love itself. The analysis of different layers of reality and its scientific methods, together with the postpositivistic recognition of the plurality of methods, has shown that the method of inference to the best explanation, which is used in the article, is a legitimate scientific method. The Christian doctrine of the Triune God of Love and the doctrine of perichoresis make perfectsense of the empirical observations and lifeworld experiences of true love. However, the question remains unanswered: which of the worldviews best explains the curious and surprising phenomenon of true love?
