The concept of the Trinity is confusing to me. I was reading an article on the differences and similarities of the three Christian traditions: Orthodox, Protestant, and Roman Catholic and I agreed and understood all the topics except the Holy Spirit.
Here is what they said:
The Orthodox believe the third person of the Trinity, proceeding from the Father alone as in the original Nicene Creed. The Father sends the Spirit at the intercession of the Son. The Son is therefore an agent only in the procession of the Spirit.
The Protestants believe the Holy Spirit proceeds from both the Father and the Son. The Nicene creed includes the 'filioque' (Latin: 'and the son').
The Catholics agree with the Protestant view.
Can someone explain and confirm?
