Let's say a Christian grew up in a non-Baptist Reformed church and was baptized as an infant. This Christian went through a catechism and confirmation during his youth (12-15 yr. old) and in the process came to a personal conviction and personal decision to make Christ his Lord and Savior. The pastor (the catechist) knew this and because of that he decided that the candidate is ready for confirmation. In the confirmation ceremony he declared his faith in the Lord Jesus Christ publicly to the congregation and by that ceremony became a full member of the church and was allowed to take communion. (See this answer for the meaning of Confirmation for a pedobaptist Reformed church).
This Christian now goes to another church, a Baptist church that practices adult full immersion, which also holds the same Reformed theology apart from baptism. Knowing the personal history of this Christian, what is the typical Reformed Baptist church policy on this?
I can think of a few options:
- Ignore the infant baptism and the confirmation completely, and treat this person like other baptism candidates
- Consider the infant baptism invalid since an infant cannot make a conscious declaration of faith, so have him re-baptized
- Do not require adult baptism, but require the person to do the remaining important element, such as making a public confession and taking a class (to update the theology) so he can then become an elder later
- Recognize the combination of Infant baptism + Confirmation ceremony to be equivalent to adult baptism since all the elements (baptism using Trinitarian formula, declaration of faith, public announcement, admittance to membership + communion) were believed and performed within the same Reformed theology framework.
In implementing the policy, can you also give an overview of pastoral approaches in Baptist churches for people who fit the case study above, i.e. were baptized as infants, catechized, confirmed, and became member of a pedobaptist Reformed church?
