As far as I can tell, Oath of Rebuke and Healing Radiance are abilities unique to Larian's interpretation of Dnd5e. The problem is, as initial implementations of new abilities, it's hard to imagine them being any more imbalanced relative to one another. There are a number of issues:
First, Healing Radiance is immediately useful while Oath of Rebuke's usefulness is immediately questionable. In the early game, having extra healing, especially healing that can be leveraged for the entire party, is at arguably its highest need as there are limited spell slots and resources for healing outside of spells. Oath of Rebuke, on the other hand, requires that a unit be hit, which is most dangerous at these levels with such a limited health pool. Even so, the return damage is very low for the two turns its granted. In a best case scenario, you'd want to be hit by a high number of enemies to maximize its usefulness, but the low hit points makes this a very bad idea.
Second, Healing Radiance's healing scales with level, while Oath of Rebuke's damage does not. This imbalance is self explanatory, but is just compounded by the first point. An ability of very questionable utility at level 1 becomes increasingly inviable at later levels, with the only bonus being able to soak more hits and therefore trigger the damage more.
In order to balance Healing Radiance, I would recommend one of two solutions:
(1) Make the damage dealt to the attacker equal to the caster's Paladin level and consider making it trigger even on a miss. (edit to add trigger recommendation)
-or-
(2) Make any attacker receive a debuff that grants attacks against them advantage for one round.
The first has hard scaling, while the second provides a buff that scales according to the increased offense potential of the party with levels.
Thanks for reading this feedback and considering it.
Warm regards.
