…To make the sign of the cross we put a hand to the head to indicate God the Father, who proceeds from no one.
When we put our hand to the middle it indicates His Son, Our Lord, who proceeds from the Father and who came right down to the womb of the most holy Virgin Mary.
When we put our hand to one side and then to the other it indicates the Holy Spirit, who proceeds from the Father and the Son.
When we join our hands, this indicates that the Three Persons are one true essence.
-St. Ignatius Loyola
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 rose 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.
Glory be to the Father and the Son and the Holy Spirit, as it was in the beginning is now, and ever shall be world without end.
