Church as prescribed by the Bible has rules. There is leadership and actually a form of government. There are certain things that happen and certain things that are not supposed to happen. Two or three gathering together and discussing Jesus is a blessing, but it isn't Church according to the Bible.
The qualifications for a Church govt do not require a PhD, but they don't exclude them either. Luke was a doctor and a man of God and part of the ministry, but nit an Apostle. Paul was highly educated in the hebrew law and spoke 3 languages. Peter was a fisherman with no known formal education before his attendance in the finest seminary for 3 years that ever existed.
1. Just because you talk to someone about Jesus doesn't mean you had Church, according to the Bible.
2. Church can happen anywhere but it happens at an appointed time, with an intended purpose and under the authority of a chosen man of God.
3. Going to and fro in the earth to talk about Jesus is a blessing, and if sanctioned by a man of God may be considered an evangelical mission. It is meant yo set up a Church, and whether or not it is Church is subject to debate.
4. A true Church has structure and even a government. Even Jesus's ministry had one.
5. If you ignore these facts, or at least don't even inquire about them to test their validity, you are ignoring scripture. If you do so, you are testifying that they don't really matter.
