The funniest thing I have seen in a long time is your silence concerning what Paul wrote in his epistle which is traditionally known as "the First Epistle to the Corinthians." That epistle was not just addressed to those of the church at Corinth but also to
"all that in every place call upon the name of Jesus Christ our Lord":
"Paul, called to be an apostle of Jesus Christ through the will of God, and Sosthenes our brother, Unto the church of God which is at Corinth, to them that are sanctified in Christ Jesus, called to be saints, with all that in every place call upon the name of Jesus Christ our Lord, both theirs and ours" (1 Cor.1:1-2).
The words found in this epistle are addressed to every single believer who lived at the time when it was written. John Nelson Darby, often called the father of modern dispensationalism, understood that to be true, writing the following:
"He addresses the assembly of God at Corinth, adding a character (the application of which is evident when we consider the contents of the epistle) 'sanctified in Christ Jesus.' Afterwards the universality of the application of the doctrine and instructions of the epistle, and of its authority over all Christians, wherever they might be, is brought forward in this address" (John Nelson Darby, Commentary at 1 Corinthians 1:2).
With these things in mind, we can understand what Paul said later in the same epistle applied to every single believer when the epistle was written:
"For as the body is one, and hath many members, and all the members of that one body, being many, are one body: so also is Christ. For by one Spirit are we all baptized into one body, whether we be Jews or Gentiles, whether we be bond or free; and have been all made to drink into one Spirit" (1 Cor.12:13).
When Paul used the words "are we ALL baptized into one Body" that can only mean that the Twelve were included and therefore they are members of the Body of Christ. Therefore, we can understand that the doctrine found in the Hebrew epistles applies to those in the Body and contain valuable information for those in the Body.
Instead of actually saying anything intelligent about these things all you do is try to prove that Paul was in error when He said that "we are ALL baptized into onre Body."
You say that you believe Paul but the only thing I see from you is that you will believe him if what he says doesn't contradict what some people told you! You do not believe him when he spoke of others who were "in Christ" before He was because someone told you that Paul was the first member of the Body of Christ.
Do you not even understand that by the time the Hebrew epistles were written Israel had been temporarily set aside? According to your ideas the believing remnant out of Israel Israel went down with a sinking ship despite the fact that Paul said that they were made members of the Body of Christ:
"But now in Christ Jesus ye who sometimes were far off are made nigh by the blood of Christ. For he is our peace, who hath made both one, and hath broken down the middle wall of partition between us; Having abolished in his flesh the enmity, even the law of commandments contained in ordinances; for to make in himself of twain one new man, so making peace; And that he might reconcile both unto God in one body by the cross, having slain the enmity thereby" (Eph.2:13-16).
Here is even more evidence from the pen of Paul that you can ignore!
