In Romans 3:10 and 3:23 we learn there are none that are righteous, not you and not even the man teaching/preaching from the pulpit. That includes people that go to the building they mistakenly call The Church.
Colossians 3:23-24 NASB1995
Whatever you do, do your work heartily, as for the Lord rather than for men, knowing that from the Lord you will receive the reward of the inheritance. It is the Lord Christ whom you serve.

I don't mistakenly call the building we gather at a church.
Technically the building was called a "church" before the people were. You see, in English we use "church" to translate the Greek word
ekklesia, meaning something like "called out assembly". But the English word "church" actually has its roots in another Greek expression,
kyriakon doma, which translates to "[the] Lord's house", a term used to describe Christian meeting places going back to the early centuries of Christianity.
This expression was shortened as kyriakon and entered into several language families, in proto-Germanic from which modern Germanic languages such as English descend, as
kirika, from which modern German
kirche, Danish
kirke, and English church--from Anglo-Saxon
circe, to Middle English
chirche, to Modern English
church. This also happened in the Slavic languages, such as Old Church Slavonic црькъви (tsr'k'vi, though my transliteration might be off), modern Bulgarian църква (tsurkva), Russian церковь (tserkov'), or Macedonian црква (tsrkva).
However, since these houses of worship is where the Faithful assembled, where they ekklesia'd, in the Romance languages (through the Latin borrowing of the Greek as ecclesia), such as Italian
chiesa. So when going to assemble you "go to church", you go to assemble for worship, you gather together for that distinctive act of Christian gathering--the Mass, the Liturgy, the Service, etc--and so the place wherein you gather, where you and your fellow Christians ekklesia together--is the assembly, the ekklesia too.
And so in English, and other Germanic languages, we took the word already used to describe the house of worship itself to refer to what we are doing, and who we are in our togetherness-in-Christ--"church".
So there is the Church, the entire assembly of Christian Faithful in its catholic or universal sense; both here on earth and in heaven.
And we go to "do" church by meeting together for the Divine Service/Liturgy/Mass where we hear the Scriptures read, hear the preaching of the word, offer songs of praise, and prayer together, and celebrate the Lord's Supper.
We do this as our local assembly or congregation, aka "church" together.
And we do this in a church, a place of assembling and congregation.
If you want to get right down to it, the Church churches as churches in churches.
I just wanted to get that out of the way. Because while its popular to say "the building isn't the church" as a kind of pious aphorism, it isn't correct.
It is perfectly acceptable to speak of going to church, to do something at the church, that we are the Church, our church, your church, etc. It's all fine. All the ways we historically use this word are etymologically and linguistically sound, and it is perfectly acceptable.
