I'd use a normal priest to bless the sacreds, or give a celestial master two astral gems for PoS/divine blessing
But assuming you mean how to do it under a no bless strat with only recruit everywhere units... Perhaps spamming some lesser water elementals with a bunch of masters of the way? Or assuming no magic, perhaps a few shielded arrow catchers for the javelins + lots of pikes to soak the lances and then horsemen flankers to punch through the armor.
