Every cleric is a battle cleric. Your most important stat will be END so you can take hits. Secondary stats are either STR or SPR. STR if just want basic damage, SPR if you'd prefer to really on critical hits and have a bit more SP and MDEF. Common builds are:
-Pure END.
-3:1 or 2:1 END:STR.
-3:1 or 2:1 END:SPR.
