This paper examines "the doctrine of justification by faith alone" by one of the greatest minds of the past, Samuel Johnson,
an influential Anglican, who argues against salvation for the infant and the mentally
handicapped because of their
impossibility of faith. The author points out that the Heidelberg Catechism stated an idea that begins to be more positive towards the salvation of infants and the mentally handicapped. The paper relates that some of the most modern concepts of the Protestant movement stress, without doubt, that their salvation is allowed.
