"9 That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved. 10 For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation. 11 For the scripture saith, Whosoever believeth on him shall not be ashamed. 12 For there is no difference between the Jew and the Greek: for the same Lord over all is rich unto all that call upon him. 13 For whosoever shall call upon the name of the Lord shall be saved."
This is often used as a prooftext for instantaneous salvation that many protestant denominations like to use. I must say that it is one of the most convincing ones i've come across. A straightforward reading here seems simple enough; make a declaration that Jesus is Lord and believe that He was raised from the dead and you will be saved. Indeed, this passage almost seems to imply a declaration of faith by pronouncement. Why is this interpretation incorrect, and how does this passage fit into Orthodox soteriology?
