The following article by Roger E Olson October 10, 2020 “What Should “Church” Be Like? Answering the Question” is excellent, it is reproduced here in its entirety.
I believe a true Christian church should be one where God is very busy changing lives and influencing its social environment with compassionate actions.
I believe a true Christian church should be countercultural in the sense of resisting accommodation to secular and pagan culture while communicating the gospel in ways people of the culture can at least understand (but without letting go of anything essential to the gospel).
I believe a true Christian church should be an extended family where at least members and regular attenders know each other, share their lives with one another, share their property with each other (not as a common purse necessarily but with genuine generosity), and love one another in spite of differences of race, gender, ethnicity, economic and social status, educational level, etc.
I believe a true Christian church should be one where the preaching and teaching covers the whole of God’s revelation including judgment, conviction, repentance, and conversion—including the call to take great risks for God’s kingdom.
I believe a true Christian Church should be one where the people know the Bible well and are led by the teaching leaders into deeper understanding of its implications for being in the world but not of it.
I believe a true Christian church should select as leaders and teachers only persons deeply committed to Jesus Christ as God, Lord, Savior, and Coming King. The leaders should be broadly and generously orthodox in terms of belief in the Trinity, the inspiration and authority of Scripture, salvation through Christ alone by grace alone through faith alone without neglecting works of love.
I believe a true Christian church should practice loving discipline of members and regular attenders who fall into sin and who do not repent and seek to change.
I believe a true Christian church should require members (including leaders) to avoid worldliness in the sense of ungodly entertainment, conspicuous consumption, immodest dress, membership in organizations that require beliefs and/or ceremonies contrary to the sole Lordship of Jesus Christ (idolatry), sexual immorality, divorce (except in cases of abandonment, abuse, or adultery), identification with hate groups and ideologies, violence (except for self-defense or defense of vulnerable people under attack), gluttony, and extreme individualism manifested in lack of faithful participation in God’s people and their mission.
I believe a true Christian church should never hide its Christian identity.
I believe a true Christian church should preach and teach the Word of God, the gospel, faithfully and in all its dimensions and aspects, live life together in love, worship God enthusiastically, train members and attenders in Christian discipleship for everyday life, reach out to help hurting and vulnerable people live human lives, care for the environment, expect miracles to happen especially in response to fervent prayer, pray for the sick and the hurting, hold members and leaders accountable to their Christian callings, speak truth to power prophetically, encourage members to seek and use the gifts of the Holy Spirit, and never be ashamed of Jesus Christ even for the sake of attracting visitors and others to fill empty pews or seats.
Finally, I believe a true Christian church should celebrate the sacraments of water baptism and the Lord’s Supper regularly.
