The Creed Continues to explain concepts it stated before: That we worship one God in trinity and the trinity in unity (line 3); and, What quality the Father has, the Son has, and the Holy Spirit has (line 7).

Lesson from the Creed

Similarly, the Father is almighty, the Son is almighty,
the Holy Spirit is almighty.
Yet there are not three almighty beings;
there is but one almighty being.

Athanasian Creed, lines 13-14

Explanation from Scripture

It belongs to God, as God, to be omnipotent, or Almighty. Thus the LORD, Yahweh, said to Abraham: I am Almighty God (Genesis 17:1 NKJV). And Yahweh is not merely God the Father, but the Triune God—the Father, the Son, and the Holy Spirit. This is confirmed in Genesis 18 when Abraham is visited by three guests, who speak as one, and are addressed as one by Abraham, and are called the LORD in Scripture (Genesis 18:13) and say: Is anything too hard for the LORD? (Genesis 18:14 NKJV)

The concept of God’s being Almighty isn’t confined to God having infinite power—though it does mean that. Rather, it especially has to do with God’s ability to perfectly perform whatever He wills. In Isaiah, God says: For I am God, and there is no other; I am God, and there is none like Me, Declaring the end from the beginning, And from ancient times things that are not yet done, Saying, “My counsel shall stand, And I will do all My pleasure” (Isaiah‬ ‭46‬:‭9‬-‭10‬ ‭NKJV‬‬).

His omnipotence is seen in both creation and redemption. For since the creation of the world His invisible attributes are clearly seen, being understood by the things that are made, even His eternal power and Godhead (Romans‬ ‭1‬:‭20‬ ‭NKJV‬‬). When we look at the universe we inhabit, we are seeing a testimony to the power of the Triune God.

Yet, in redemption, we see God’s power turned to our salvation. The Father plans, chooses, calls, and draws: All that the Father gives me will come to me, and whoever comes to me I will never cast out … And this is the will of him who sent me, that I should lose nothing of all that he has given me, but raise it up on the last day. For this is the will of my Father, that everyone who looks on the Son and believes in him should have eternal life, and I will raise him up on the last day (John‬ ‭6‬:‭37‬, ‭39‬-‭40‬ ‭ESV‬‬).

The Son not only accomplishes redemption by His death and resurrection; He Himself gives eternal life to whomever He will: For as the Father raises the dead and gives life to them, even so the Son gives life to whom He will (John‬ ‭5‬:‭21‬ ‭NKJV‬‬).

Moreover, the Son has been given power over heaven and earth, for the sake of His Church. Not only authority (Matthew 28:18) but power. The power of the Father and the Son coalesce in our redemption, for Scripture speaks of the exceeding greatness of His [the Father’s] power toward us who believe, according to the working of His mighty power which He worked in Christ when He raised Him from the dead and seated Him at His right hand in the heavenly places, far above all principality and power and might and dominion, and every name that is named, not only in this age but also in that which is to come. And He put all things under His feet, and gave Him to be head over all things to the church, which is His body, the fullness of Him who fills all in all (Ephesians‬ ‭1‬:‭19‬-‭23‬ ‭NKJV‬‬, emphasis added).

And this is fitting, for Scripture says of the Son: For by Him all things were created that are in heaven and that are on earth, visible and invisible, whether thrones or dominions or principalities or powers. All things were created through Him and for Him. And He is before all things, and in Him all things consist (Colossians‬ ‭1‬:‭16‬-‭17‬ ‭NKJV‬‬). Likewise, we read that the Son upholds the universe by the word of his power (Hebrews 1:3 ESV).

The Son, then, as the Father, is Almighty in both creation and redemption. So when Scripture declares that all things work together for good to those who love God, to those who are the called according to His purpose (Romans‬ ‭8‬:‭28‬ ‭NKJV‬‬); do not doubt that the Son is bending every detail of history to His will, moving it inevitably towards then end God purposed at the beginning, for the good of His Church. It is for this very reason it was given to Him to be head over all things to the church (Ephesians 1:22).

The Son is likewise Almighty to resurrect and perfect His saints when He returns. So we read Christ will transform our lowly body that it may be conformed to His glorious body, according to the working by which He is able even to subdue all things to Himself (Philippians‬ ‭3‬:‭21‬ ‭NKJV‬‬).

And the power by which He will raise us is the power which resurrected Him—the Holy Spirit. For it says: But if the Spirit of Him who raised Jesus from the dead dwells in you, He who raised Christ from the dead will also give life to your mortal bodies through His Spirit who dwells in you (Romans‬ ‭8‬:‭11‬ ‭NKJV‬‬).

Christ will raise you to glory by the Spirit, and this same Spirit is in you, sanctifying you now, conforming you to Christ in this life: But we all … are being transformed into the same image from glory to glory, just as by the Spirit of the Lord (2 Corinthians‬ ‭3‬:‭18‬ ‭NKJV‬‬).

Likewise, the Spirit is working in power now, not just in the individual saints, but to empower the Church by freely distributing His good gifts among us: There are diversities of gifts, but the same Spirit … [O]ne and the same Spirit works all these things, distributing to each one individually as He wills (1 Corinthians‬ ‭12‬:‭4‬, ‭11‬ ‭NKJV‬‬).

When we confess that the Triune God is Almighty, we are confessing the infinite power of the Father, the Son, and the Holy Spirit to accomplish every jot and tittle of God’s eternal purpose in creation and redemption.
