Mythic Warpriest

Sacred Weapon wrote:

Weapons wielded by a warpriest are charged with the power of his faith. In addition to the favored weapon of his deity, the warpriest can designate a weapon as a sacred weapon by selecting that weapon with the Weapon Focus feat (if he has multiple Weapon Focus feats, this ability applies to all of them)...

Select one group of weapons from the list of fighter weapon groups. You gain proficiency with all weapons in this group. If you possess a feat such as Weapon Focus that requires you to choose a kind of weapon, you can instead apply the effects of that feat to all weapons from that weapon group. When wielding a weapon from that group, add a number equal to your tier to your CMD against disarm and sunder attempts made against that weapon. You can select this ability more than once. Each time you select this ability, it applies to a different weapon group.

So, can a Warpriest with Weapon Focus (greatsword) that has selected Mythic Weapon Training use his Sacred Weapon ability with all weapons in that weapon group?

Yikes, RAW that certainly seems to be the case, so your Weapon Focus (greatsword) would become Weapon Focus (heavy blades).

Good thing my group unanimously house ruled that you only gain the sacred weapon bonuses to the deities favored weapons and the Weapon Focus you get from the class itself.
