Thank you very much for your advice. I've taken some cuttings in case the plant does not revive, and I will also follow your suggestion. As i look at other images of other "Christmas cacti", I see that the leaves are much different than mine. They have sharper looking edges while mine is more rounded. Have I (and family members before me) been incorrectly calling this plant a Christmas cactus? Now, on to my final question; I have owned this plant for 5 years and never has it bloomed. My father had it for 15 - 25 years before me, and before him another relative had it for an undetermined amount of time. According to my dad, the plant never once bloomed. Not sure about it's life before he had it. Is this abnormal? If i am incorrectly calling it a Christmas cactus, is it instead some variety that does not bloom?
