The Blessed Trinity

How can God be one and three?

3 lessons

The Trinity is the central mystery of the Christian faith, and the one most often explained badly. This unit teaches it precisely enough to avoid the classic errors, and shows why it is a truth God revealed rather than one reason could work out.

Lessons

LessonBig question
3.1 One God, three PersonsIsn’t “three in one” a contradiction?
3.2 Processions and relationsHow are the Persons distinct if each is fully God?
3.3 The Trinity and usDoes any of this make a difference to my life?

The lessons in this unit are being written. Until they are ready, the readings below cover the same ground in more depth.

Philosophy you will need

Watch out for

The popular analogies mislead. Water, ice and steam suggest one Person appearing in three ways; a three-leaf clover suggests three parts. Lesson 3.1 shows why both get the Trinity wrong.
