Um...no.
Jesus commanded His disciples to go and make disciples. That was His Missio Dei.
Quote:
"For the Son of Man came to seek and to save what was lost."
~ Luke 19:10
Hmm...let's see, that's the founder speaking.
Here's another from Jesus where He instructs His disciples to follow His Missio Dei:
Quote:
16Then the eleven disciples went to Galilee, to the mountain where Jesus had told them to go. 17When they saw him, they worshiped him; but some doubted. 18Then Jesus came to them and said, "All authority in heaven and on earth has been given to me. 19Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, 20and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age."
~Matthew 28:16-20 Emphasis mine
Its not certain organized sects or denominations of Christianity. Its every one. Its "the Way" as in "the Way, the Truth, and the Life." In a word, its foundational, because the Founder left it with us.
But it is much more than that also. For instance Jesus taught that kindness and charity and compassion should flow out from those who follow Him as disciples:
Quote:
18A certain ruler asked him, "Good teacher, what must I do to inherit eternal life?"
19"Why do you call me good?" Jesus answered. "No one is good—except God alone. 20You know the commandments: 'Do not commit adultery, do not murder, do not steal, do not give false testimony, honor your father and mother.'"
21"All these I have kept since I was a boy," he said.
22When Jesus heard this, he said to him, "You still lack one thing. Sell everything you have and give to the poor, and you will have treasure in heaven. Then come, follow me."
23When he heard this, he became very sad, because he was a man of great wealth. 24Jesus looked at him and said, "How hard it is for the rich to enter the kingdom of God! 25Indeed, it is easier for a camel to go through the eye of a needle than for a rich man to enter the kingdom of God."
26Those who heard this asked, "Who then can be saved?"
27Jesus replied, "What is impossible with men is possible with God."
28Peter said to him, "We have left all we had to follow you!"
29"I tell you the truth," Jesus said to them, "no one who has left home or wife or brothers or parents or children for the sake of the kingdom of God 30will fail to receive many times as much in this age and, in the age to come, eternal life."
~ Luke 18:18-30
Then the Lord's brother James the Apostle echoes it:
Quote:
"Religion that God our Father accepts as pure and faultless is this: to look after orphans and widows in their distress and to keep oneself from being polluted by the world."
~James 1:27
And so does the Apostle Paul:
Quote:
"But if a widow has children or grandchildren, these should learn first of all to put their religion into practice by caring for their own family and so repaying their parents and grandparents, for this is pleasing to God."
~ 1 Tim 5:4
And that is our "organized" religion.
