Salty, it seems like no one wants to address your question. Since I am in the camp of which you speak, I will try to do so.For those of you who believe you can loose your salvation: after you have "lost your salvation"
1) do you need to be re-baptized
2) do you need to be voted into church membership again
3) does a pastor/deacon/elder need to be ordained again?
And no - this is not a facetious question.
1. Most people who believe you can lose your salvation also believe in baptismal regeneration. For these people baptism a second time is as useless as getting circumcised a second time, actually impossible. Of course, losing one's salvation doesn't nullify 1 John 1:9 so forgiveness is very possible provided you have been baptized once.
However, for those who don't believe in baptismal regeneration (e.g.., Free Will Baptists), the practice could vary widely. If the person coming back in wanted to be re baptized most churches would do it. Some may even require it if the person had been removed from the church roll.
2. This presumes that one has been removed from church membership. That happens only once every century or so in my church. Frankly I see no connection between losing salvation and being removed from church membership.
3. Same as my answer to No. 2, supra.
