Explain how Lewis uses the image of “good infection” to describe Christian transformation, and state one limit of the image.

### Why this is right Lewis uses “good infection” to stress that Christian life is received through contact with Christ rather than produced independently. The image points to participation and transformation, not a literal biological process. ### The concept Lewis’s analogies make an abstract theological claim easier to approach: being close to a source of life allows a person to share in what that source has. He connects this to the claim that Christ gives humans Zoe. As with all analogies, the image does not explain the divine process completely; Lewis warns that no comparison is identical to God’s action. ### What a good answer covers - Contact with Christ as the means of sharing new life. - The difference between transformation and merely copying moral teaching. - A limit of the biological infection analogy. ### Remember The image explains participation in Christ’s life, not a literal transfer of disease.
