A player in my group asked the DM:
- What if Cleric 1 was to cast spirit guardians and go for the heart
of battle - Then Cleric 2 cast sanctuary on him
- Then Cleric 1 just sits there not actively attacking, probably
taking the Dodge action while keeping concentration on his spell.
This makes it OP because he would be sitting there dishing out massive damage, while enemies would have to make a DC 15 Wisdom saving throw to hit him, and if they actually succeed they would have to hit with disadvantage due to the Dodge action.
The crucial point lies in the wording of sanctuary:
If the warded creature makes an attack or casts a spell that affects an enemy creature, this spell ends.
Cleric 1 cast spirit guardians before sanctuary came into effect, so he will not attack or cast something for the time being; he just sits there.
But he is also keeping concentration on a spell that harms others.
What do you think? Does the sanctuary spell end or not?

As of the 2018 errata, if an enemy takes damage from your spirit guardians spell, your sanctuary spell ends
The description of the sanctuary spell (PHB, p. 272) originally said:
However, the 2018 PHB errata added "deals damage to another creature" to the list of conditions that end the sanctuary spell. The description of the sanctuary spell now reads (emphasis mine):
Even though the spirit guardians spell doesn't directly affect an enemy creature when cast, it does deal damage to them:
As a result, the sanctuary spell ends as soon as an enemy takes damage from a spirit guardians spell cast by the warded creature.
Even before the 2018 errata, the intent was that damaging an enemy would end the spell (though this was not reflected in the description of the spell). In an unofficial tweet in July 2016, rules designer Jeremy Crawford stated:
Clearly, the 2018 PHB errata changed the spell so that it now works as intended.
