Oh, you do not.

Sephiroth can be defeated from level 50 onwards quite easily. Have a healer always on standby and have the other two characters deal all the damage. Barrier, MBarrier and Haste are good spells to cast. Hero Drinks to increase your damage. Should be a breeze.

F2, I2, B2, Q2
I think you're problem is that you don't even have the 3rd and most powerful forms of these rudimentary materia. By your stage of the game, you should definitely have Fire3, Ice3, Bolt3 and Quake3. That's not to say that you should be using them, but it's a clear indication of how ineptly you've used materia.
