My personal preference:
100~150CON, rest into INT/SPR.
INT has rank up bonus. which means better damage into the future.
SPR is great for ur buffs, such as Blessing and Stone Skin.
Aspersion dmg is affected by both SPR and INT.
I see u enjoy party support. I’d go SPR.
To me Chaplain is a hidden class, a class that has no future ranks. You sealed off 1 rank for it. And for this case, its mostly for just 1 skill, explained below.
Chaplain gives u Aspergillium < the reason u chose this class. Its damage is great against dark type enemies, which are plenty. I have a chaplain which does 5.1k per aspergillium strike (counting attributes and buffs etc.) while only 2.Xk dmg on enemies that are not weak to Holy. Adding the fact that our AA rarely hit more than 2 targets, AND needs us to go up close and personal… thats what made me reroll 
^ of course ur experience may differ, but that was mine. IMO make ur CON hit 100 ASAP.
Last Rites, another sacrament. With buff limitation, u gotta decide if it is worth taking up a slot. U may need to buy Daino scrolls or decide to not use some buffs as it can overide yours/ur party members.
Magnus and Capella are both crap. One needs another skill as a pre req, and setting up is -.-… the other, especially with buff limit and such, keeps overwriting urs and ur team buffs.
If support is ur style, Kirvis will be a better option. However take cleric2 asap. 10 tiles healing is a lotta different.
Might want go Kirvis > PD after cleric 2 if u are an INT type.
edit: If u would continue with ur build, i’d put Sacrament at level 1 since u could buy it off pardoners. Resurrection put it to Lv4, Revive could be lower, but it depends on how u feel.
