On Pentecost Christ gave us a church not a bible. THAT church which existed 1400 years before Martin Luther came along midwifed God’s word into the canon of Scripture which ML thought he was fit to abridge.
On Pentecost, Christ gave us the Holy Spirit, who breathed out Scripture through those He indwelt.
Those born again then became the church and it's still growing today.
The body of Christ is an organism, not an organization.
