Is God's grace age-based?
Moreover, belief in divine Scripture declares to us that among allwhether infants or those who are olderthere is the same equality of the divine gift...Otherwise, it would seem that the very grace which is given to the baptized is given either more, or less, depending on the age of the receivers. However, the Holy Spirit is not given with measure...For although the infant is still fresh from its birth, yet it is not such that anyone should shudder at kissing it in giving grace and in making peace. (Cyprian), 250 AD 5.354
Cyprian was not an apostle nor is what he wrote scripture.
