the prayer Trump did not join in followed by an earlier version- apostles creed vs Niacene Creed; perhaps he did not join because it is a modern version lacking clarity:

I believe in God, the Father almighty, creator of heaven and earth. 

I believe in Jesus Christ, his only Son, our Lord. He was conceived by the power of the Holy Spirit and born of the Virgin Mary. 

He suffered under Pontius Pilate, was crucified, died, and was buried. He descended to the dead. 

On the third day he rose again. He ascended into heaven, and is seated at the right hand of the Father. He will come again to judge the living and the dead. 

I believe in the Holy Spirit, the holy catholic Church, the communion of saints, the forgiveness of sins, the resurrection of the body, and the life everlasting. 

Amen.

vs

I believe in one God the Father Almighty,

Maker of heaven and earth,

And of all things visible and invisible:

And in one Lord Jesus Christ, the only-begotten Son of God,

Begotten of his Father before all worlds,

God of God, Light of Light,

Very God of very God,

Begotten, not made,

Being of one substance with the Father,

By whom all things were made;

Who for us men, and for our salvation came down from heaven,

And was incarnate by the Holy Ghost of the Virgin Mary,

And was made man,

And was crucified also for us under Pontius Pilate.

He suffered and was buried,

And the third day he rose again according to the Scriptures,

And ascended into heaven,

And sitteth on the right hand of the Father.

And he shall come again with glory to judge both the quick and the dead:

Whose kingdom shall have no end.

And I believe in the Holy Ghost,

The Lord and giver of life,

Who proceedeth from the Father and the Son,

Who with the Father and the Son together is worshipped and glorified,

Who spake by the Prophets.

And I believe in one Catholick and Apostolick Church.

I acknowledge one Baptism for the remission of sins.

And I look for the Resurrection of the dead,

And the life of the world to come.

Amen
