“Dreams save us. Dreams lift us up and transform us. And on my soul, I swear — until my dream of a world where dignity, honor and justice becomes the reality we all share — I’ll never stop fighting. Ever.”
The iconic “I fight for Truth, Justice and the American Way.”
The Pledge of a Superman, from World’s Finest Comics #213:
“I will use this power for all the good that can be done… To work for peace… To encourage virtue… And above all, to preserve life, in all its forms… Or failing in that, to give up this power… forever!”
Krypto the Superdog was part of the Space Canine Patrol Agency, whose slogan is as follows: “Big Dog! Big Dog! Bow wow wow! We’ll crush evil… Now, now, now!” “Big dog, big dog, bow wow wow” is a Shout-Out to the Yale chorus (“Bulldog, bulldog, bow wow wow…”).
Announcer: On your knees for the Master! The hour has come! HE has come! Who is beyond good and evil? Who is the prophet of Anti-Life? Who is the Rock and the Chain and the Lightning? All powerful! All unforgiving! All conquering! WHO IS YOUR NEW GOD NOW AND FOREVER? Darkseid: Darkseid is.
In Final Crisis, Darkseid gets a new Badass Creed. He only uses it once, but it qualifies because he says it using the possessed bodies of billions of people.
Darkseid: I. Am. The. New. God. All is one in Darkseid. This mighty body is my church. When I command your surrender, I speak with three billion voices. When I make a fist to crush your resistance. It is with three billion hands. When I stare into your eyes and shatter your dreams. And break your heart. It is with six billion eyes! Nothing like Darkseid has ever come among you: Nothing will again. I will take you to a hell without exit or end. And there I will murder your souls! And make you crawl and beg! And die! Die! Die for Darkseid!
Barry declares what it means to be the Flash as he runs himself to death saving the entire multiverse in JLA Incarnations #5:
“Light calling to me… drawing me forward… what is it? I hear it in my heart. The essence of what I am. The source and the end. Speed itself. It reminds me. What I stand for. What the League stands for. My life doesn’t matter. I can save them. If I just let go… And then I am in it and I am a part of it and I am everywhere. I am the lightning and I am reaching out. And there are no accidents!”
The Golden Age Sandman, as revived in the 1990s Sandman Mystery Theatre series: “None can escape the Sandman’s dark dream.”
He also used to leave a poem on his defeated opponents: “There is no land beyond the law / Where tyrants rule with unshakable power! / ‘Tis but a dream from which the evil wake / To face their fate, their terrifying hour!”
“Keep faith. Trust to love. Fight with honor. But fight to win.”
In Wonder Woman: Warbringer the Amazons have an oath about protecting the world from evil they have to make to become Amazons, just like in The Golden Age of Comic Books. Also just like in the Golden Age this oath is only alluded to and described rather than given to the reader; however the oath of loyalty Amazons make to their Amazon sisters is given:
Sister in battle, I am shield and blade to you. As I breath, your enemies will know no sanctuary. While I live, your cause is mine.

From the Legion of Super Heroes (2006), we have the Legion Oath, which first appeared when Timberwolf was inducted into the fold, and later in Season 2, as recited by the Legion as a whole.
To the Legion of Super Heroes, I make this solemn pledge:
To use my powers for good,
To fight for justice and protect the innocent,
To aid my fellow Legionnaires in times of peril,
And to keep their secrets safe.
We are the Legion of Super Heroes. Long Live the Legion!
