I said, not past their dispensation . . .
Dispensationalism is non-biblical.
In the Bible the word “dispensation” never refers to a period of time. Invariably its meaning is “a stewardship,” “the act of dispensing,” “an administration.” Read the four New Testament texts in which the word “dispensation” is found: 1 Corinthians 9:17; Ephesians 1:10; 3:2; and Colossians 1:25. Weymouth’s translation of 1 Corinthians 9:17 reads: “A stewardship has nevertheless been entrusted to me.”
1 Corinthians 12:12-13
For even as the body is one and yet has many members, and all the members of the body, though they are many, are one body, so also is Christ. For by one Spirit we were all baptized into one body, whether Jews or Greeks, whether slaves or free, and we were all made to drink of one Spirit.
Ephesians 3:6
That the Gentiles should be fellow heirs (as the Jews), and of the same body, and partakers of his promise in Christ by the gospel:
John 10:16
And other sheep I have, which are not of this fold: them also I must bring, and they shall hear my voice; and there shall be one fold, and one shepherd.
Colossians 1:24
Who now rejoice in my sufferings for you, and fill up that which is behind of the afflictions of Christ in my flesh for his body’s sake, which is the church
The Church, orthodoxy - Catholic, Orthodox, oriental, Assyrian - even the others who follow orthodox teachings as encapsulated in the Nicene creed, are the body of Christ
So, show me where it says that the ability to forgive was to be ended with the apostles, or at least show me why it is no longer needed.
As a second comment, your ‘past their dispensation’ makes no sense whatsoever and isn’t backed up by anything. In other words, it’s an attempt to start with an answer, then find a way to prove it.
