The celebration of Pentecost, the birthday of the Church fifty days after Easter, is immediately followed by the Solemnity of the Most Holy Trinity. Thus, this weekend we celebrate the Solemnity of the Most Holy Trinity, the liturgical feast that celebrates the central mystery of the Christian faith. This is the most singularly distinctive belief that separates Christianity from all other religions. For instance, Islam and Judaism hold firmly onto mono personal monotheism that does not admit the multiplicity of persons in the one true God. As a consequence, for strict adherents of Judaism, the doctrine of the Trinity is both erroneous and heretical, the same doctrine is judged extremely offensive to strict muslims.
