1. How does the church today mimic the church described in the chapter? How does it not?
Again, I think these are pretty weak questions that are so broad that cannot be answered without going through the entire chapter. To ask for the church as a whole is almost impossible to describe. Are they talking about the Southern Baptist realm, or all Christian denominations. Even to go with one denomination would be pretty difficult since each church is autonomous. Anyway, most churches try to mimic the ministries and sacraments that are described in Scripture. Each church may have a different interpretaion of passages, but hold to their beliefs based on their interpretation. Again, I don't think this is very good question, I hope I gave enough reasons and answered sufficiently for you all.

How do you Define Church?

The Church is the body of Christ. Made of many parts coming together to work for one purpose (1 Cor. 12). The Church is also the Bride of Christ, submitting to the Lord and waiting for his guidance and Love (Eph 5). Most of all it is God's followers. Not a building, or place to worship, but a community that is committed to the Lord.
