That photo shows how much better our digital cameras are today. It was taken at the turn of this century (wow! Amost quarter of a century ago!) and after years of storms and winds, no replacements. That's a sign of good workmanship. My husband built it because we had a new gymnasium/fellowship hall on the left, and our sanctuary and classroom building on the right. We also had a beautiful young lady in a wheelchair that needed to go across. Our children were all involved in pouring the concrete. I have a beloved photo of them pouring concrete for the ramps.

Now, let me ask you - What is "church"? Which building? Is the pass through part of the church. It might surprise you that the Greek word translated "church" in our New Testament dose not refer to any of the buildings involved in our church meeting. Here's the Strong's definition from e-Sword:

G1577

ἐκκλησία

ekklēsia

ek-klay-see'-ah

From a compound of G1537 and a derivative of G2564; a calling out, that is, (concretely) a popular meeting, especially a religious congregation (Jewish synagogue, or Christian community of members on earth or saints in heaven or both): - assembly, church.

 But it's a bit deeper in Blue Letter Bible online:

There is no part of a "church" in the above photo. However, all the people involved in building that pass through are a part of the church because they fit under 1.D.ii. At one time both my husband and I, and our three children were a part of the congregation that meet in the buildings, a part of a congregation of baptized believers of Jesus, Christ, Son of God.

Everyone who does believe John 3:16-18 will be happy to tell you about Jesus and their eternal life. They've made a commitment to Him to follow in His steps, even if it takes the same path. That's part of following the most important commandments:

Master, which is the great commandment in the law? Jesus said unto him, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind. This is the first and great commandment. And the second is like unto it, Thou shalt love thy neighbour as thyself. On these two commandments hang all the law and the prophets. (Matthew 22:36-40 KJV)

There is a lot of work for everyone of us to keep those two commandments. Yet doing so, we are working within "all the law and the prophets." Christian was the label given to people in Antioch, not by their fellow believers, but by non-believers who recognized they were different. Christians should be different because they are in the world but not of the world. One of the things Christians are to do is:

Not forsaking the assembling of ourselves together, as the manner of some is; but exhorting one another: and so much the more, as ye see the day approaching. (Hebrews 10:25 KJV)

Thus we gather - for some on the Sabbath, for others on the first day of the week to worship our rison savior. For centuries it has been a tradition to call the building where the congregations meet a "church." I don't have a problem with that, along as it is understoon that people who look to Jesus as their savior are the true church, the body of Christ:

So we, being many, are one body in Christ, and every one members one of another. (Romans 12:5 KJV)

For as the body is one, and hath many members, and all the members of that one body, being many, are one body: so also is Christ. (1 Corinthians 12:12 KJV)

For the perfecting of the saints, for the work of the ministry, for the edifying of the body of Christ: (Ephesians 4:12 KJV)

Let no man therefore judge you in meat, or in drink, or in respect of an holyday, or of the new moon, or of the sabbath days: Which are a shadow of things to come; but the body is of Christ. (Colossians 2:16-17 KJV)
