What is your favorite creed or oath that you have experienced?

Obviously, although if I had been promoted to an NCO that would probably be a choice creed as one recites it in front of their peers. Many people's favorite Creed though,
U.S. Army - The Infantryman's Creed

I am the Infantry.
I am my country's strength in war.
her deterrent in peace.
I am the heart of the fight-
wherever,
whenever.
I carry America's faith and honor against her enemies.
I am the Queen of Battle.

I am what my country expects me to be-
the best trained soldier in the world.
In the race for victory
I am swift,
determined,
and courageous,
armed
with a fierce will to win.

Never
will I betray my country's trust.
always I fight on-
through the foe,
to the objective,
to triumph over all,
If necessary, I will fight to my death.

By my steadfast courage,
I have won 200 years of freedom.
I yield not to
weakness,
to hunger,
to cowardice,
to fatigue,
to superior odds,
for I am mentally tough,
physically strong,
and morally straight.

I forsake not-
my country,
my mission
my comrades,
my sacred duty.

I am relentless.
I am always there,
now and forever.

The medical creed: Do no harm. After that it would have to be the Boy Scouts': Be prepared.

My favorite oath is my US Army commissioning oath [at bottom].
My favorite creed would be a Christian creed such as the Apostle's Creed or the Nicene Creed [below]. SFC Joe S. Davis Jr., MSM, DSL
We believe in one God,
the Father almighty,
maker of heaven and earth,
of all things visible and invisible.
And in one Lord Jesus Christ,
the only Son of God,
begotten from the Father before all ages,
God from God,
Light from Light,
true God from true God,
begotten, not made;
of the same essence as the Father.
Through him all things were made.
For us and for our salvation
he came down from heaven;
he became incarnate by the Holy Spirit and the virgin Mary,
and was made human.
He was crucified for us under Pontius Pilate;
he suffered and was buried.
The third day he rose again, according to the Scriptures.
He ascended to heaven
and is seated at the right hand of the Father.
He will come again with glory
to judge the living and the dead.
His kingdom will never end.
And we believe in the Holy Spirit,
the Lord, the giver of life.
He proceeds from the Father and the Son,
and with the Father and the Son is worshiped and glorified.
He spoke through the prophets.
We believe in one holy catholic and apostolic church.
We affirm one baptism for the forgiveness of sins.
We look forward to the resurrection of the dead,
and to life in the world to come. Amen.
My favorite oath is my commissioning oath:
I do solemnly swear (or affirm) that I will support and defend the Constitution of the United States against all enemies, foreign and domestic; that I will bear true faith and allegiance to the same; and that I will obey the orders of the President of the United States and the orders of the officers appointed over me, according to regulations and the Uniform Code of Military Justice. So help me God."
