In the next patch, at level 44 Paladins will have a new spell available to them called "Hammer of Wrath". This spell, useable only on wounded targets is a ranged attack which does holy damage. This spell is primarily designed to give Paladins greater control when fighting enemies which choose to flee.
Since my initial post brought forth more questions than answers, I gathered some specfic details to share with you. Please be aware that what's listed below applies to the final rank of the spell - available at level 60.
And I realize that the lack of specifics can be upsetting. The fact is, the information contained in my sticky thread is a precise layout of what's under extensive review for the Paladin over the next several weeks. As research is completed and decisions finalized, more concrete information will become available.
