What are Christian healing and Christian Science?

"In the year 1866, I discovered the Christ Science or divine laws of Life,
Truth, and Love, and named my discovery Christian Science." - page 107

"The physical healing of Christian Science results now, as in Jesus' time,
from the operation of divine Principle, before which sin and disease lose
their reality in human consciousness and disappear as naturally and as
necessarily as darkness gives place to light and sin to reformation. Now,
as then, these mighty works are not supernatural, but supremely natural.
They are the sign of Immanuel, or 'God with us,' -- a divine influence ever
present in human consciousness and repeating itself, coming now as was
promised aforetime,

To preach deliverance to the captives [of sense],
And recovering of sight to the blind,
To set at liberty them that are bruised." - page xi

Christian healing is healing through the power of the Christ as practiced by
Christ Jesus, his disciples, and apostles. Through her prayer and dedicated
study of the Bible, Mary Baker Eddy discovered the laws of Christian healing
and named her discovery Christian Science. Her book, Science and Health
with Key to the Scriptures, is the complete, authoritative description of
Christian Science. Here are a few passages from her book.

"Our Master [Jesus] healed the sick, practised Christian healing, and
taught the generalities of its divine Principle to his students; but he left no
definite rule for demonstrating this Principle of healing and preventing
disease. This rule remained to be discovered in Christian Science." -
