I'm afraid they trust in the water of baptism . . . not the blood. Do you have a link to a sermon where a man is saved by simple faith in Jesus Christ (like the thief on the cross?)
I am not a believer of the Church you are addressing. However, I wanted to respond after noticing your comment about the thief on the cross.
I follow Peter's instructions in Acts 2:38 as well. Unfortunately a lot of people miss the fact that most of us who follow the steps outlined do definitely rely first and foremost on the sacrifice of our Lord and Savior. Without the shedding of His blood all of mankind would be lost. But praise God because of His grace we are given a path back to right standing with our maker.
As far as the thief on the cross, his obligation differed from the New Testament Church...
Have you ever wondered how the thief on the cross entered into Paradise without following the New Testament covenantal responsibilities outlined in Acts 2:38? “Repent, and be baptized everyone of you in the name of Jesus Christ for the remission of sin, and ye shall receive the gift of the Holy Ghost.”
Even if the thief wanted to be obedient, coming down off of the cross was not an option. How then is it possible that Jesus could tell the thief that he would be with Him that day in Paradise?
In order to be saved, the man beside Jesus would have been responsible to meet God’s Old Testament commands because Jesus had not died and resurrected yet.
The New Testament rebirth requirements began after Jesus’ death, burial, resurrection and ascension into the heavens. We know this because on the day that the church was born, Peter stated that we must repent, be water baptized in Jesus name, and
receive the Holy Ghost in order to be saved. The Holy Ghost was not sent until after Jesus ascended back into Heaven and poured His blood upon the mercy seat. (Hebrews 9:11-12) After Jesus entered the Holy of Holies in the Heavenlies, the Holy Ghost (gift of the Holy Ghost) was then poured out upon the people present on the Day of Pentecost. (Acts 2:3-4)
Let’s look at when the New Covenant officially began. We know from scripture that John the Baptist’s ministry was to prepare the way of the Lord. He was referred to as the Baptist, because in addition to proclaiming the coming of the Lord, his ministry was to initiate the concept of water baptism. Water baptism was necessary for the remission of sin. (Acts 2:38) However, sins could not be remitted without the shedding of blood. After Jesus’ blood was shed it had to be poured onto the mercy seat. This had not taken place prior to John’s ministry.
Jesus appeared after His resurrection and fulfilling the mission as our high priest, returned for a period of 40 days and then ascended back into Heaven. After this occurred, individuals who had been baptized by John were commanded to be re-baptized in Jesus name. (Acts 19:2-6) The New Testament church had officially begun.
Keep in mind that a Will and Testament becomes valid only after one’s death. This being said, you may wonder what the thief’s covenantal responsibility would entail. The Old Testament was still in effect at the time of the thief’s death.
Each person, including the thief on the cross, that perished before Jesus entered into the holy place and obtained eternal redemption for mankind, was judged by the Old Testament mandates. The obligation to God was to have faith in the coming Messiah and to be circumcised.
Genesis 17:10 states, “This is my covenant, which ye shall keep, between me and you and thy seed after thee; Every man child among you shall be circumcised... He that is born in thy house, and he that is bought with thy money, must needs be circumcised: and my covenant shall be in your flesh for an
everlasting covenant. And
the uncircumcised man child whose flesh of his foreskin is not circumcised,
that soul shall be cut off from his people; he hath broken my covenant.”
The New Testament parallel of the Old Testament circumcision is found in Colossians Chapter 2: “In whom also ye are circumcised with the circumcision made without hands, in putting off the body of the sins of the flesh by the
circumcision of Christ: Buried with him in baptism, wherein also ye are risen with him through the faith of the operation of God, who hath raised him from the dead.”
p...I almost feel, that I must insert "disclaimers", in these oh so "politically correct" days. So, to avoid the "holier then thou", and "racially bigoted" deflectings, from those who view themselves, AS such! With their double standarded unstable lifestyles, and corrupted ways, and natures!) The term "G-Man", (least where I learned it from), came from old Jimmy Cagney, Edward G. Robinson, Humphrey Bogart, movies, where they were playing gangsters during the "days of prohibition." Think there was even a movie called "G Man", where Jimmy Cagney signed up to become a federal law enforcement agent. Before it was known as the federal bureau of investigation....Maybe not, though! (they say there's 3 ways to tell when one is getting older! 1 is the loss of memory! I forget the other 2!
