Not a Lutheran, but I used to be.
I was baptized, raised, confirmed in the Lutheran Church. Until I left home, the church was the center of our family life. My three best friends became Lutheran pastors.
I married a Catholic girl, continued to identify myself as a Lutheran, but occasionally we attended catholic Mass.
In 1990 I felt a calling to Catholicism, which in retrospect was clearly the work of the Holy Spirit, but I suppressed the call.
In 2004, after attending a funeral Mass for my mother in law, the call increased in intensity…I still ignored it, even though I clearly heard it.
In 2008 my wife and I visited Rome and on a whim decided to visit Vatican City. We made it into the square, even though we were advised we may not be let in because we didn’t have tickets for the Wednesday blessing by Benedict Xvi, but we ended up literally feet away from him, and I was moved to almost tears. We were standing outside one of the chapels in St. Peter’s and an usher outside the chapel took me by the arm and led us to the pews saying, “it would be a shame for a believer to come all the way to the Vatican and not attend a Mass”!
My wife and I moved to South Korea on business for a year and we regularly attended Mass on a nearby Army base. three years ago, at age 57, and after returning home, I entered the church the week before Lent.
I cherish and thank God for my Lutheran roots. My faith as a Lutheran made my conversion to Catholicism easy and swift…8 weeks into RCIA the rel ed director and pastor told me they wanted me to consider enter in full communion with the church so I could experience Lent as a Catholic with my wife instead of waiting for the Easter vigil.
Now, back to your concern, although similar in many ways to Catholicism (but surely different in many others), I never really got what God’s relationship with me, and mine with him, was all about until I entered the Catholic Church!
I am praying for you!
