Well, I personally do not think thats a good reason. First, I am a teacher in Georgia, and I grew up in Georgia and I am Catholic. While the majority of my friends are Baptist as well, you can always meet a Catholic friend as well. If the children stay involved in the parish throughout childhood and teenage years they should be fine, and meet Catholic friends as well as baptist friends. Its not like you cant be friends with non- catholic people!
Second, being Baptist means all them would need to be re-baptized (they only believe in believers baptism) the CC does not believe you need to be Baptized twice, and neither does the bible!
They believe in Sola Scriptura- that the bible is the sole means of rule and doctrine. If they turn Baptist one thing they will learn, is A LOT about the bible which is not a bad thing. Their bible (all protestants) also has 7 less books then the Catholic bible. Each church kinda does its own thing, but they would probably belong to the Southern Baptist Convention.
They believe that Jesus is only symbolically present in the Eucharist, and only have communion once a month or a few times a year.
They only have those 2 sacraments not seven.
They dont have intercession through Mary or the Saints.
They believe if you accept Jesus into your heart you will be saved and never lose that salvation (once saved always saved)..
Here's the thing that may cause them to convert or not. Since I have a lot of friends who are Baptist I know this is a BIG southern Baptist belief, but not ALL baptists believe this.. But they think Catholics are going to hell. That they are not really saved. Because we "bow down to statues, we worship Mary, we sacrafice Jesus over and over on the Cross again at Mass.." etc. This will be something that will come up living in the South amongst some Baptist friends. And if they convert to become Baptist they will probably attack your faith at some point.
While being baptist would have them learn a lot about the bible, I would not suggest that they leave the faith that Jesus himself established with the 7 sacraments.
Hope this helps!
