should we go to church while our own body is the temple of God??

I went to church yesterday afternoon, yeah, it was my first day to the church after about 6 months not to go there. Do not laugh at me, because I know most of the youth of today like that. that is why, when I was in church, I look around me and found that most of the congregation are adults and children. There's only a small part youth who came with her boyfriend. (I'm sure it's just to convince parents of the man's girlfriend if he was a religious person).
well, because I have not been to church, when I was there and followed the eucharist ceremony, I found myself not memorize some of the dialogue in the ceremony. wow, I'm very lazy ...when I realized that I was very far from God, how sad I am. I feel myself a fool. and well, I promised the Lord to come to church every week. it was time I became a dutiful daughter to God, right?
of all that, there are things that I confused. Bible says that the human body is the temple of God (Corinthians 3:16), but we must still go to church to pray. should we go to church while our own body is the temple of God???
but when I think back, I conclude that, for the Catholics, we need to go to church to receive the sacrament of the Eucharist every week, even every day. receive unleavened bread that has been blessed as a symbol of Christ's body.
well, at least I've got a reassuring answer. but what about the others? I do not know. indeed of religion in society is very sensitive, can lead to civil war in a country (wow!!).so, let us accept each other as a religious community. so we can live happily ever after, side by side.
