The New Testament church was different in that everybody participated in the meeting:

We used 1 Corinthians 14:26 as one example of what a NT church meeting was like.

It's quite likely that the single person monologue seen in church today had its origin in the state backed church Constantine created.
It led to ministry and authority vested in a few, which is antithetical to the New Testament model:
John 13:14 NET If I then, your Lord and Teacher, have washed your feet, you too ought to wash one another’s feet.
Maybe a Bible study best resembles the original church, and thus the best place for your friend to get his feet wet (and washed!). I learnt the most in discussions at studies, both online and off.
How did Jesus purify the Church? By explaining the Scriptures to them:
Luke 24:25-27 NET So he said to them, “You foolish people – how slow of heart to believe all that the prophets have spoken! Wasn’t it necessary for the Christ to suffer these things and enter into his glory?” Then beginning with Moses and all the prophets, he interpreted to them the things written about himself in all the scriptures.
Ephesians 5:25-27 NET Husbands, love your wives just as Christ loved the church and gave himself for her to sanctify her by cleansing her with the washing of the water by the word, so that he may present the church to himself as glorious – not having a stain or wrinkle, or any such blemish, but holy and blameless.
Christ's work is continued by his disciples who wash each other's feet . How is this different from the one person monologue?
There are checks and balances built into the process when the disciples imitate Christ:
Acts 17:11 NET These Jews were more open-minded than those in Thessalonica, for they eagerly received the message, examining the scriptures carefully every day to see if these things were so.
The building action spoken of here are the explanations we extract from the Scripture, which must be buttressed by other Scripture, and based on the teachings of the Apostles, Prophets, which are in turn based on teachings of Christ:
1 Corinthians 3:12-13 NET If anyone builds on the foundation with gold, silver, precious stones, wood, hay, or straw, each builder’s work will be plainly seen, for the Day will make it clear, because it will be revealed by fire. And the fire will test what kind of work each has done.
Jeremiah 23:28-31 NET Let the prophet who has had a dream go ahead and tell his dream. Let the person who has received my message report that message faithfully. What is like straw cannot compare to what is like grain! I, the Lord, affirm it! My message is like a fire that purges dross! It is like a hammer that breaks a rock in pieces! I, the Lord, so affirm it! So I, the Lord, affirm that I am opposed to those prophets who steal messages from one another that they claim are from me. I, the Lord, affirm that I am opposed to those prophets who are using their own tongues to declare, ‘The Lord declares….’
As you can see, this edification model makes up for what the monologue lacks, by having a regulating mechanism: footwashers using the water of the Word of God to expose truth or lie in claims about the meaning of God's word.
