Sree,
here are some verses in which the word "church" (singular) may not refer to a "local church":
1 Corinthians 10:32 (KJV)
Give none offence, neither to the Jews, nor to the Gentiles, nor to the church of God:
Acts 8:3 (KJV)
As for Saul, he made havock of the church, entering into every house, and haling men and women committed them to prison.
1 Corinthians 15:9 (KJV)
For I am the least of the apostles, that am not meet to be called an apostle, because I persecuted the church of God.
Ephesians 5:23 (KJV)
For the husband is the head of the wife, even as Christ is the head of the church: and he is the saviour of the body.
any others?

If Jesus is writing a separate letter just because the situations are different makes no sense. He could have still written a single letter addressing all the different situation, right? For example I can write a single letter to a family addressing all the members of it, even though their situations are different.
I can prove this from scripture itself. Let us see how Jesus was dwelling among Churches.
Rev 12-13:- Then I turned to see the voice that was speaking with me. And having turned I saw seven golden lampstands; and in the middle of the lampstands I saw one like a son of man, clothed in a robe reaching to the feet, and girded across His chest with a golden sash.
What are these 7 distinct lampstands?
Verse 20-
As for the mystery of the seven stars which you saw in My right hand, and the seven golden lampstands: the seven stars are the angels of the seven churches, and the seven lampstands are the seven churches.
So each Church was represented by an individual lampstand here. A lampstand has 7 branches, so if all the Churches are part of one body, then each Church should represent different branch of a single lampstand, instead they are all individual lampstands! How can Jesus make it so clear to us that each Church is individual body by itself? In OT it was Israel represented by a single lampstand but now each Church it self represented by a single lampstand.
"
brother, I do not invalidate the distinction of the local church. I think like the Trinity, the Father, Holy Spirit and our Lord Jesus are distinctly God, yet One God.

in 1 Corinthians 12, where Paul talks about "one body" is he just talking about a local church? If that so, this ideal of diversity of gifts and function may not be applicable to other churches. I think the diversity of giftings and callings make sense when we have a view of the universal church, the body of Christ.
and in Ephesians 4:
4There is one body, and one Spirit, even as ye are called in one hope of your calling;
5One Lord, one faith, one baptism,
6One God and Father of all, who is above all, and through all, and in you all.
7But unto every one of us is given grace according to the measure of the gift of Christ.
8Wherefore he saith, When he ascended up on high, he led captivity captive, and gave gifts unto men.
9(Now that he ascended, what is it but that he also descended first into the lower parts of the earth?
10He that descended is the same also that ascended up far above all heavens, that he might fill all things.)
11And he gave some, apostles; and some, prophets; and some, evangelists; and some, pastors and teachers;
12For the perfecting of the saints, for the work of the ministry, for the edifying of the body of Christ:
