The beginning of the Nicene Creed refers to God as Father and Almighty.
I believe in one God, the Father Almighty
What do those two names mean to you?
For one, they are ways you can know God. Names are one way God describes himself to us. As Basil, a fourth century church father, pointed out in Against Eunomius:
There is no one name that is adequate to give complete description of God. Rather, there are many names for him, each of which has its own particular meaning…. Taken together they afford us only a small and unclear knowledge of God’s nature, but this is still adequate enough for our purposes.”1
Our purposes are to glorify God and enjoy him forever. His names help us to do that. With his names he comforts us, he humbles us, and he causes us to sing the with the angels:
“Holy, holy, holy, is the Lord God Almighty, who was and is and is to come!” (Rev. 4:8, ESV)
