i wouldn’t say acknowledging parts of doctrine and what they are for is blasphemous or they wouldn’t have taught it in scripture.
This is true
“for this is my blood of the new testament, which is shed for many for the remission of sins.”
Matthew 26:28 KJV
This is true also
“To him give all the prophets witness, that through his name whosoever believeth in him shall receive remission of sins.”
Acts 10:43 KJV
This also is true doctrine of God
“Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins,
and ye shall receive the gift of the Holy Ghost.”
Acts 2:38 KJV
this is the Truth
“For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures;”
1 Corinthians 15:3 KJV
This Also true of those who get baptized in his name
“Know ye not, that so many of us as were baptized into Jesus Christ were baptized into his death? Therefore we are buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life.”
Romans 6:3-4
truth john said this
“I indeed have baptized you with water:
but he shall baptize you with the Holy Ghost.”
Mark 1:8
also true Jesus said this
“Jesus answered, Verily, verily, I say unto thee, Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God.”
John 3:5
then just look at what they did they baptized people in water for remission of sins in Jesus name ……
