Trinity Icon (Andrei Rublev)

We believe in one God, the Father almighty, maker of all things, visible and invisible;

And in one Lord Jesus Christ, the Son of God, begotten from the Father, only-begotten, that is, from the essence of the Father, God from God, light from light, true God from true God, begotten not made, of one essence with the Father, through Whom all things came into being, things in heaven and things on earth, Who because of us men and because of our salvation came down and became incarnate, becoming man, suffered and rose again on the third day, ascended to the heavens, and will come again to judge the living and the dead;

And in the Holy Spirit.

The doctrine of the Holy Trinity is not merely an “article of faith” which men are called to “believe.” It is not simply a dogma which the Church requires its good members to “accept on faith.” Neither is the doctrine of the Holy Trinity the invention of scholars and academicians, the result of intellectual speculation and philosophical thinking.

The doctrine of the Holy Trinity arises from man’s deepest experiences with God. It comes from the genuine living knowledge of those who have come to know God in faith.

I arise today
Through a mighty strength, the invocation of the Trinity,
Through belief in the Threeness,
Through confession of the Oneness
of the Creator of creation.

I arise today
Through the strength of Christ’s birth with His baptism,
Through the strength of His crucifixion with His burial,
Through the strength of His resurrection with His ascension,
Through the strength of His descent for the judgment of doom.

I arise today

What are church schisms and why do they arise? And if the Lord reveals the truth to us to the extent that we can contain it, how do we know which side is right? Since the time of the First Ecumenical Council, the Church has been struggling with this disease, but it keeps coming up again and again.

Where do heresies come from?

The Arian dispute, which split the Church in the fourth century, raged for almost a hundred years, and its consequences were felt even longer. It all began with the arrival in the Church of many educated people who were keenly interested in the kinds of problems that few people cared about previously. And different understandings of the Trinity of the Godhead emerged.
