Sorry to hear you and your wife are leaving Catholicism for the MS Lutheran Church. I was MS Lutheran for my first 33 years of life, then converted to Catholicism, receiving First Communion on my wedding day in 1984, and I've never looked back.
The reason I converted was to receive the Sacraments, the Most Holy Eucharist [so I could partake in "
His strength and His power" too], not just because I was marrying a Catholic.
