The concept of church is not what Jesus taught. A church is not the means in which we form our covenant with the Lord. One does not need to be in the house of man to connect to Jesus Christ. Simply turn a rock or split a piece of wood and you will find our Lord and Savior. The true church is in your heart, your mind and your soul. All other churches have failed.
16 And he came to Nazareth, where he had been brought up: and, as his custom was, he went into the synagogue on the sabbath day, and stood up for to read.
Luke 4 KJV
It is within the power of all, therefore, in every Church, who may wish to see the truth, to contemplate clearly the tradition of the apostles manifested throughout the whole world; and we are in a position to reckon up those who were by the apostles instituted bishops in the Churches, and to demonstrate the succession of these men to our own times; those who neither taught nor knew of anything like what these [heretics] rave about. For if the apostles had known hidden mysteries, which they were in the habit of imparting to the perfect apart and privily from the rest, they would have delivered them especially to those to whom they were also committing the Churches themselves. For they were desirous that these men should be very perfect and blameless in all things, whom also they were leaving behind as their successors, delivering up their own place of government to these men; which men, if they discharged their functions honestly, would be a great boon to the Church, but if they should fall away, the direst calamity.
-Saint Irenaeus
