Introduction
The mystery of the most Holy Trinity is a basic doctrine of faith
in Christianity, understandable not with our heads but with our hearts. It teaches
us that there are three distinct persons in one God, sharing the same divine nature.
Our mind cannot grasp this doctrine which teaches
that 1+ 1+ 1 = 1 and not 3. But we believe
in this mystery because Jesus who is God taught it clearly, the evangelists recorded
it, the Fathers of the Church tried to explain it and the Councils of Nicaea and Constantinople defined it as a dogma
of Christian faith.
