Perhaps the principal reason why false teaching has allured those honestly seeking Truth, is the cleverness of the counterfeit.
From an external point of view and to those outside Christian Science the work of one falsely taught, and of the Scientist in the beginning appears to be the same— but how widely different the aims.
To one falsely taught, mortal mind is real and a part of God's creation, which by some unknown means has become contaminated and his aim is to renovate, reform, purify, and make this real mind a perfect reflection of the Divine Mind by ignoring the claims of error and affirming the good— thus unconsciously giving the claims of error an opportunity to multiply indefinitely.
