Mark,
“On the sabbath day we went outside the gate by the river, where we supposed there was a place of prayer; and we sat down and spoke to the women who had gathered there. A certain woman named Lydia, a worshiper of God, was listening to us; she was from the city of Thyatira and a dealer in purple cloth. The Lord opened her heart to listen eagerly to what was said by Paul. When she and her household were baptized, she urged us, saying, “If you have judged me to be faithful to the Lord, come and stay at my home.” And she prevailed upon us. (Acts, chapter 16:13-15)

What is not ‘formal’ Church about this?
What is not ‘formal’ about Paul speaking the Truth, people believing the Word, and a baptism?
“Then Jesus came to them and said, “All authority in heaven and on earth has been given to me. Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, and teaching them to obey everything I have commanded you.”
