How long does adult confirmation take in the Catholic faith?
If you have been baptized i the name of the Father, the Son and the Holy Spirit, you do not need to be re-baptised as long as you can prove it ( certificate or two witnesses). Otherwise, you would receive a conditional baptism. RCIA starts in the fall, and candidates are received into the Church at the Easter Vigil Mass. There is no requirement to be Cahtolic in order to marry a Catholic.
