“The one who believes
And is baptized
Will be saved.
But the one
Who does not believe
Will be condemned!”
ὁ πιστεύσας καὶ βαπτισθεὶς σωθήσεται, ὁ δὲ ἀπιστήσας κατακριθήσεται.
This longer addition of Mark, is like the addition in Matthew, chapter 28:19-20. Once again, there was an emphasis on baptism that was not mentioned prior to the death and resurrection of Jesus. This Mark addition said that the one who believed (ὁ πιστεύσας) and was baptized (καὶ βαπτισθεὶς) would be saved (σωθήσεται). However, anyone who did not believe (ὁ δὲ ἀπιστήσας) would be condemned (κατακριθήσεται). Thus, this recommendation also brought a condemnation. Belief and baptism were important.
