The "sect" - prefer "denomination", sounds less pompous - doesnt matter.
Churches/denominarions/sects dont go to heaven - PEOPLE who believe the gospel (Jesus Christ's died for our sins, was buried and ressurrected) go to heaven.
1 Corinthians 15
1Moreover, brethren,
I declare unto you the gospel which I preached unto you, which also ye have received, and wherein ye stand;
2By which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain.
3For I delivered unto you first of all that which I also received, how that
Christ died for our sins according to the scriptures; 4And that he was buried, and that he rose again the third day according to the scriptures:
5And that he was seen of Cephas, then of the twelve:
6After that, he was seen of above five hundred brethren at once; of whom the greater part remain unto this present, but some are fallen asleep.
7After that, he was seen of James; then of all the apostles.
8And last of all he was seen of me also, as of one born out of due time
