I'd like to respond to this myself and quote a man far greater than I:
it is Bernard de Clairvaux's treatise "In Praise of the New Knighthood" I'm taking this from, and to me, it defines chivalry and knighthood as a whole:
"Thus in a wonderous and unique manner they appear gentler than lambs, yet fiercer than lions. I do not know if it would be more appropriate to refer to them as monks or as soldiers, unless perhaps it would be better to recognize them as being both. Indeed they lack neither monastic meekness nor military might."
to be humble, yet strong
to be quiet, yet wise
to be meek, yet courageous
to be selfless
to be loyal
that to me, is the knight in my heart, and why the Templar kit was such an inspirational and emotional journey for me to undertake. It's very different than dressing up as a Clansman of the O'Neills, defending my kith and kin, or being a Gallogaleigh going to the highest bidder. That to me is the difference between a Knight and other forms of warriors.
