I’m a Catholic convert from the LCMS, raised by an LCMS pastor in fact (and my brother is one now as well).
My wife is a cradle Catholic, although that is not the only thing that pulled me into Catholicism. In fact I was quite adamant when we first married that while my wife could go to Mass as much as she wanted and I’d even go with her sometimes, we were going to be members of an LCMS church and raise our kids in the LCMS.
The LCMS in our area is rapidly declining though, and there is really not an LCMS congregation around here that is alive and vital–I believe within the next few years some will close and some will join the ELCA. Speaking of which, in my desperation not to be Catholic I attended an ELCA congregation for a while, until I found out that their employee health plan funds elective abortion.
When my son was born I wanted to have my dad baptize him, and my wife agreed based on the fact that the Catholic Church recognizes Lutheran baptisms as valid. But the problem of raising our son in a divided home made me reconsider my staunch “never going to be Catholic” position and I decided to find out what the Church teaches about itself, as opposed to what I thought I knew about the Church from Lutheran school, and I thought if I could “stomach” authentic Catholic teaching then I wanted to become a Catholic so that my wife and I could be unified in our faith and thus be better able to pass on the faith to our kids.
So one night I stayed up all night reading There We Stood, Here We Stand as well as just about every tract here at Catholic Answers. I spoke with the priest at my local parish, who dumped me into RCIA. I attended a couple of sessions led by a deacon who wanted to talk about virtually nothing other than his views on illegal immigration, and it was at that point that I realized that as a baptized Christian I did not need to go through RCIA:
Because they have already been baptized, they are already Christians; they are, therefore, not catechumens. Because of their status as Christians, the Church is concerned that they not be confused with those who are in the process of becoming Christians.
“Those who have already been baptized in another church or ecclesial community should not be treated as catechumens or so designated. Their doctrinal and spiritual preparation for reception into full Catholic communion should be determined according to the individual case, that is, it should depend on the extent to which the baptized person has led a Christian life within a community of faith and been appropriately catechized to deepen his or her inner adherence to the Church” (NSC 30).
I brought this to the attention of the parish director of faith formation, and after asking me some questions to make sure I was sufficiently catechized in the Catholic faith, she scheduled me to be received into the Church through the Rite of Reception at a Sunday Mass.
