According to the good domain in PFSRD, an 8th level cleric can bestow a weapon with the special weapon quality, 'holy'
Holy Lance (Su): At 8th level, you can give a weapon you touch the holy special weapon quality for a number of rounds equal to 1/2 your cleric level. You can use this ability once per day at 8th level, and an additional time per day for every four levels beyond 8th.
and according to weapon quality Holy, a weapon can bestow a negative level to evil creatures
It bestows one permanent negative level on any evil creature attempting to wield it. The negative level remains as long as the weapon is in hand and disappears when the weapon is no longer wielded. This negative level cannot be overcome in any way (including by restoration spells) while the weapon is wielded.
As the power does not specify a save for 'attended objects', but a 'touch' does a cleric get the ability to use a melee touch attack to make a weapon, or even an improvised weapon like a shield, 'holy' and either disarm or cause a negative level to the evil creature holding it?
