Do Lutherans and Catholics have the same beliefs regarding the purpose of Confirmation? As a Catholic, I believe that I received a greater outpouring the Holy Spirit at Confirmation. 


  Baptism, the Eucharist, and the sacrament of Confirmation together constitute the "sacraments of Christian initiation," whose unity must be safeguarded. It must be explained to the faithful that the reception of the sacrament of Confirmation is necessary for the completion of baptismal grace. For "by the sacrament of Confirmation, [the baptized] are more perfectly bound to the Church and are enriched with a special strength of the Holy Spirit. Hence they are, as true witnesses of Christ, more strictly obliged to spread and defend the faith by word and deed." - Catechism of the Catholic Church


However, my understanding is that for Lutherans, confirmation is a more of an affirmation of baptism.

In the Lutheran faith confirmation is not a sacrament as it is for Catholics.  According to the book of Concord Article XIII(VII) confirmation does not meet the criteria which make a sacrament as it is not required by Gods direct command nor is there a clear promise of grace associated with it.  I would say the caveat exists that it is at conformation where people first receive communion as it marks that they now have fellowship with other Lutherans of their denomination.
