Conditional baptism: Mainline Christian theology (including Roman Catholic, Eastern Orthodox, Oriental Orthodox, Church of the East, Anglican, Lutheran and most other Protestants) has traditionally held that only one baptism is valid to confer the benefits of this sacrament.  In particular, the Council of Trent defined a dogma that it is forbidden to baptize a person who is already baptized, because the first baptism would make an indelible mark on the soul.  Likewise, "Methodist theologians argued that since God never abrogated a covenant made and sealed with proper intentionality, rebaptism was never an option, unless the original baptism had been defective by not having been made in the name of the Trinity."  Therefore, in cases where the validity of a baptism is in doubt, a "conditional" baptism may be performed.
