The context of the Acts period is very much seen in the institution and maintenance of the Lord's supper as revealed by Paul in 1 Corinthians. Mid-Acts believers beware, taking Israel's spiritual food could be dangerous! For more detail on the Lord's supper and mid acts see the topic on the Lord's supper.
The answers are No and No.
Though a conclusion is affirmed correct this does not mean that the logical process used to attain the result is correct. It is not simply good enough to have a correct conclusion we must have correct argumentation. A mid-acts view of the scriptures will lead to some incorrect conclusions and ultimately to faith that is shipwrecked. Lets look at the subject of baptism and statements Paul has made in 1 Corinthians.
The logic goes something like this:
A concordance of the expression "this is my body" gives the following results:
The Olive Tree - are we graft in? This question seems to have an obvious answer. "Of course we are graft into the olive tree because that is what Romans 11:17 says!" Lets read it together:
17 (AV) And if some of the branches be broken off, and thou, being a wild olive tree, wert graffed in among them, and with them partakest of the root and fatness of the olive tree;
17 (TR) ει δε τινες των κλαδων εξεκλασθησαν συ δε αγριελαιος ων ενεκεντρισθης εν αυτοις και συγκοινωνος της ριζης και της πιοτητος της ελαιας εγενου
Before answering this we will back up a little and discover important and interesting contextual information about the book we are reading from. The epistle of Paul to the Romans is a book of huge consequence because it lays down some very clear truths concerning justification by faith in the Lord Jesus Christ. This is undeniable and is affirmed by the present author. But what is also true and must also be equally affirmed is that the book is written in an age when Jew was first Rom. 1:16
Some who defend the mid-Acts position say that "because Christ is the head of the church present in the book of Acts and is also the head of the church that is mentioned by Paul from prison that we cannot assume any fundamental difference between these two companies" -- I am quoting because I don't believe their assumptions are correct nor do I believe their conclusions are correct.
When I began my christian life at the age of 21 in a small Baptist chuch in rural New Zealand I knew little of the bible and even less of its doctrine. I knew that I was saved by grace and that was a huge step from darkness to light, while not a library of knowledge it at least found me secure in the beloved.
"This know also, that in the last days perilous times shall come. For men shall be lovers of their own selves..." 2 Timothy 3:1-2
The prevailing sign of the "last days" will be a misplacement of love. The love of man will far exceed the love of God and His Son. The love of man will far exceed one's love for integrity truth, righteousness and holiness. In fact, statements in favor of the truth are now proclaimed as "hate speech" in many quarters.
The book of Ephesians is the high water mark of PAul's prison ministry. It relates to us both the circumstances and content of the revelation of "the mystery" which was hid in God. All saints immediately prior to this revelation believed and held to the hope which was proclaimed to them in the Acts and therefore would need to be adjusted to the new and unprophesied hope that was now their's by grace.
Eph 3:8 Unto me, who am less than the least of all saints, is this grace given, that I should preach among the Gentiles the unsearchable riches of Christ;
Eph 3:8 (TR) εμοι τω ελαχιστοτερω παντων των αγιων εδοθη η χαρις αυτη εν τοις εθνεσιν ευαγγελισασθαι τον ανεξιχνιαστον πλουτον του χριστου
The greek word translated "unsearchable" is the adjective ἀνεξιχνίαστος which is found here and in Rom. 11:33 where it is translated "past finding out".
Eph. 6.15 (AV) And your feet shod with the preparation of the gospel of peace;
Eph. 6.15 (TR) και υποδησαμενοι τους ποδας εν ετοιμασια του ευαγγελιου της ειρηνης
