Bonus Proficiencies

When you choose this domain at 1st level, you gain proficiency with heavy armor and martial weapons. You also gain resistance to cold damage, and the ray of frost cantrip.

Chilling gaze

Also starting at 1st level, you gain the capability to use the powers of your icy presence to instill fear into those who oppose you. When a creature within 5 feet of you that you can see attempts to hit you with an attack and misses, you can use your reaction to cause the creature to make a wisdom saving throw. The creature takes 2d8 cold damage on a failed saving throw and is also frightened by you until the start of your next turn on a failed saving throw, but suffers no consequences on a successful one. 

You can use this feature a number of times equal to your wisdom modifier (a minimum of once). You regain all expended uses when you finish a long rest.

Channel Divinity: Chilling presence

Starting at 2nd level, you can use your Channel Divinity to expel an icy blast from your chilled core. 

As an action, you present your holy symbol and all areas within 30 feet radius of you becomes difficult terrain, and all hostile creatures within that radius must make a Constitution saving throw. A creature takes cold damage equal to 2d10 + your Cleric level on a failed save, and half as much damage on a successful one. Creatures that have total cover from you are unaffected.

You also starting at this level are no longer hindered by difficult terrain conserning any icy or snowy terrain (dm decides if a terrain classifies)

Icy touch

Beginning at 6th level, whenever you deal cold damage to a creature, that creature makes a Constitution saving throw or gets its movement speed halved. They also make this saving throw at the end of each of their turns. When a creature succeeds on the saving throw, they are no longer affected my the Icy Touch and can not be affected by it for an hour.

Divine Strike

At 8th level, you gain the ability to infuse your weapon strikes with divine energy. Once on each of your turns when you hit a creature with a weapon attack, you can cause the attack to deal an extra 1d8 cold damage to the target. When you reach 14th level, the extra damage increases to 2d8.

Improved Chilling Presence

Starting at 17th level, Your Chilling Presence now deals 1d10 cold damage to all hostile creatures that enter or begin their turn within its radius. You also gain an immunity to cold damage.
