in any case and speaking to no one person in particular, the op asks the question if one can be saved WITHOUT a personal decision for Christ and the answers are confusing to say the least
the final answer is no and here is why:
there is not salvation without belief in Jesus. you cannot inherit it, you cannot be born a Christian and you cannot use church membership or any other way to be saved.
8Then Peter, filled with the Holy Spirit, said to them, “Rulers and elders of the people!
9If we are being examined today about a kind service to a man who was lame, to determine how he was healed,
10then let this be known to all of you and to all the people of Israel: It is by the name of Jesus Christ of Nazareth, whom you crucified but whom God raised from the dead, that this man stands before you healed.
11This Jesus is
‘the stone you builders rejected,
which has become the cornerstone.’
a
12Salvation exists in no one else, for there is no other name under heaven given to men by which we must be saved.” Acts 4
the Bible does not present a confusing response to the question of how one is saved and the same goes for baptism
ONLY believers who had placed their faith in Jesus were baptized (I am not referring to John the Baptist's work in the Jordan ... I am referring only to baptism AFTER the ascension of Jesus so please do not read into what I am saying here) the baptism was then and is now, a public testimony of identification with Jesus in burial (immersion) and then new life in Him...rising out of the water
an infant cannot make that kind of decision and has no concept of identifying with Christ. infants are usually 'baptized' with a sprinkling on the head rather than immersion so that does not follow with obedience to the Christian being baptized either
again, the Bible does not record one single infant being baptized
With this in view, infant baptism is not a Biblical practice. An infant cannot place his or her faith in Christ. An infant cannot make a conscious decision to obey Christ. An infant cannot understand what water baptism symbolizes. The Bible does not record any infants being baptized. Infant baptism is the origin of the sprinkling and pouring methods of baptism - as it is unwise and unsafe to immerse an infant under water. Even the method of infant baptism fails to agree with the Bible. How does pouring or sprinkling illustrate the death, burial, and resurrection of Jesus Christ?
baptism does not save people in any case. ONLY belief in Jesus sacrifice and acceptance of Him is what saves.
we had a number of months ago, a couple of people insisting you are not saved if you are not baptized . however, baptism follows salvation and is not salvation
