Is Church Membership Biblical?

The quote at the end by William Perkins may make someone judge the book wrongly (as it sounds strange to say the least) but most of the book has good arguments for being part of a church in way such as membership.
In case some of you may wonder, the quote is as follows: “The church is the suburbs of the city of God and the gate of heaven and therefore, entrance must be made into heaven in and by the church...”. I don't know the author's view on salvation so can't comment on that but his view on membership seems quite good.
