Greetings my long lost brother. You knew me by another name from years past. I served as a Champion within the Vile Crusaders back in the Space Marines 360 era. It warms my twin hearts to see another kinsmen.

I admire your strong spirit. But without the support of the gods and their teachings you are not but a bolter without a hand to aim it.
Fight alonside the Word Bearers and you will be a truly fearsome warrior

The warp is fickle - our own strength is all we have to rely on. I don't need faith - I've heard it pouring from the mouths of too many weak mortals, begging for divine assistance in fear of me and my brothers - their prayers were not answered. All I need is to be in Midnight Clad, with spare clips for my Bolt Pistol, a sword in my hand and enemies to fight. The Long War is out there in the Imperium, not inside a Temple.

I'm happy to fight alongside you when our purposes converge, but I kneel and beg for no-one! Don't cross us like those fools Abaddon and Huron Blackheart and I will happily crush Imperialist scum by your side - sacrifice any of my brothers to your gods and I'll give you more pressing reasons to pray to them, right before I send you to meet them!

My favorite Word Bearer character is Argel Tal (from the book "The First Heretic").

It is great to see you again my long lost brother. Together let us purge all of Ultramar.

Ultramar shall burn

And Maccrage shall be the altar upon which all of Gulliman's Whoresons shall burn.

I shall personally rip Robert Gulliman from whatever restoration vat they house him and mount his corpse upon the hull of my flag ship.

Greetings fellow brothers of the Wordbearers, The warriors of the Forgotten sons of prospero greet you

Hail warrior of the the forgotten sons. Your cousins of the Word have not forgotten you
