Feast of the Holy Trinity

The doctrine of the Holy Trinity, in the first centuries of the Church, was a topic held to be of great importance. As with the teaching on the Incarnation the Church had to struggle to fend of inadequate understandings of its fundamental truths. These misunderstandings, if they are stubbornly maintained by their proposers, become heresies and have the potential, like cancer cells in the body, to destroy the whole. Fortunately, we no longer hand over such people to the civil authorities to be burned but heresy remains a delict or crime in Canon Law under canon 1364. According to canon 751 "Heresy is the obstinate denial or obstinate doubt after the reception of baptism of some truth which is to be believed by divine and Catholic faith." This should not prevent us from searching more deeply into the truths of the faith. It is only when we obstinately hold on to our own mistaken idea that we are in danger of heresy. Such a verdict has to be reached by a church tribunal. Thus, we should always desist from calling other people heretics and enter into discussions with them in good of the faith striving to edify each other by what we say, think and do.
