Her 1896 book Lessons in Truth, A Course of Twelve Lessons in Practical Christianity is now considered one of the core texts on Unity Church teachings. It is the most widely read book in that movement. It has sold over 1.6 million copies since its first publication, and has been translated into eleven languages and braille.

In the late 1860s, she decided to pursue the field of medicine, and enrolled in the Homeopathic Medical College of the State of New York She graduated in 1871 and became one of the first woman physicians in America.

She was inspired and influenced by Biblical teachings and the philosophy of Ralph Waldo Emerson. She was taught by Emma Curtis Hopkins, the New Thought "teacher of teachers" and a student of Christian Science and Mary Baker Eddy.
Cady associated with several prominent figures in the New Thought movement of the time, including: Emma Curtis Hopkins, Divine Science minister Emmet Fox, Ernest Holmes, founder of Religious Science, and Charles and Myrtle Fillmore, co-founders of Unity Church. Finding The Christ in Ourselves, a pamphlet she had written and sent unsolicited to Charles and Myrtle Fillmore, was published by them in the October 1891 issue of Thought. Beginning in 1892, a series of articles titled Lessons in Truth by Dr. Cady were published in Unity magazine. This material later was compiled into a book and was the first book Unity published.
