Oh boy this means more info blogs for me in the future. lol

Eternal Flames are basically the much stronger versions of the Holy Flames, also known as Blessed Flames. The Holy Flames themselves are the most powerful level of flames, surpassing that of even the flames of Ignis, the literal embodiment of Fire itself. The flames of the Angels, the highest ranked beings in the Xros Revolution cosmology.

To put into perspective, Ignis can create flames no mortal can replicate and are so powerful that even the strongest fire artes in the series cannot stand against them. Aside from Holy Flame Artes, which easily overpower Ignis' flames. Eternal Flames are the much stronger variations of the Holy Flames, that not has the added effect of burning...well....eternally, unless the user does not will it. And unlike the other flames including the Void Flame, Eternal Flames cannot be used by anyone without Quasar Dragon blood.

So basically, Eternal Flames and Void Flames are the second strongest flames in the series.
