Juan's description is not quite correct. Actually, an op amp gain of 1 (100% feedback) is the worst-case for op amp stability. If it's stable at a gain of 1 it will be more stable at higher gains (less feedback). Some high frequency op amps are not even compensated for a gain of 1, only for gains greater than 1 (such as ≧5).
