You are referring to the Nicene Creed which mention “light from light, true god from true god”. This is the prayer Trump did not recite. I like the old catholic tradition and I don’t say the Nicene Creed either. I prefer the old traditional Apostles Creed below (or the one I grew up saying).
This is the apostles creed:
I believe in God, the Father Almighty, Creator of heaven and earth; and in Jesus Christ, His only Son, our Lord; Who was conceived by the Holy Spirit, born of the Virgin Mary, suffered under Pontius Pilate, was crucified, died, and was buried. He descended into hell; the third day He arose again from the dead. He ascended into heaven, and sits at the right hand of God, the Father Almighty; from thence He shall come 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 life everlasting. Amen.
