So, to begin.
The Nicene-Constantinoplian Creed
I believe in one God, the Father almighty,maker of heaven and earth,of all things visible and invisible.I believe in one Lord Jesus Christ,the Only Begotten Son of God,born of the Father before all ages.God from God, Light from Light,true God from true God,begotten, not made, consubstantialwith the Father;Through him all things were made.For us men and for our salvationhe came down from heaven,and by the Holy Spirit was incarnateof the Virgin Mary,and became man.For our sake he was crucifiedunder Pontius Pilate,he suffered death and was buried,and rose again on the third dayin accordance with the Scriptures.He ascended into heavenand is seated at the right hand of the Father.He will come again in gloryto judge the living and the deadand his kingdom will have no end.I believe in the Holy Spirit,the Lord, the giver of life,who proceeds from the Father and the Son,who with the Father and the Sonis adored and glorified,who has spoken through the prophets.I believe in one, holy, catholic,and apostolic Church.I confess one baptism for the forgiveness of sinsand I look forward to the resurrectionof the dead and the life of the world to come.Amen.
"In many and various ways God spoke of old to our fathers by the prophets, but in these last days he has spoken to us by a Son."26 Christ, the Son of God made man, is the Father's one, perfect and unsurpassable Word. In him he has said everything; there will be no other word than this one. St. John of the Cross, among others, commented strikingly on Hebrews 1:1-2:
- In giving us his Son, his only Word (for he possesses no other), he spoke everything to us at once in this sole Word - and he has no more to say. . . because what he spoke before to the prophets in parts, he has now spoken all at once by giving us the All Who is His Son. Any person questioning God or desiring some vision or revelation would be guilty not only of foolish behavior but also of offending him, by not fixing his eyes entirely upon Christ and by living with the desire for some other novelty.27
