[Petronski]

When he posted the Greek form for “doth also now save”; it is the present, active, indicative.

In contrast to the past tense in the previous verse. Peter is saying "Baptism saves." He is not saying "those who have been Baptized are continually thereby saved."

like everything else in Protestant theological fantasies, this one stems from lack of reading comprehension.

[enat]

“Peter is saying “Baptism saves.” He is not saying “those who have been Baptized are continually thereby saved.”

Then the aorist tense for undefined action would have been used, not the present tense which is used for action taking place at the time. “Baptism is now saving”
