Yes. The True Church, after the writings of the Apostles and Evangelists, talks about the Church having Jesus Christ as its Head, while the Church itself (humans, both alive and dead) constitute His Body. Therefore, you can’t disassociate from the Church as a Christian anymore than you can disassociate from humanity as a person.
'Applying the Bible' is what we are called to do [James 1:22]. If we don’t apply it, the Bible becomes nothing more than a boring book of words, narratives and commands.
Jesus began His earthly ministry by preaching the Gospel. "From that time Jesus began to preach, saying, ‘Repent, for the kingdom of heaven is at hand" [Matthew 4:17] and concluded it by sending out His apostles to preach and continue His work, "Go therefore and make disciples of all nations… teaching them to observe all that I have commanded you. And behold, I am with you always, to the end of the age” [Matthew 28:19–20].
The early Christians gathered daily. Gathering together for teaching, worship, edification, and fellowship. We can read the Bible or sing on our own; we cannot enjoy fellowship by ourselves. In fact, Corporate Worship is a Biblical Command [Hebrews 10:24-25].
Spiritual Gifts are part of the very nature of God, given to us to impact the Church. But most of the "churches" today have ushered out the Holy Spirit, and these "barren" churches do not hesitate to identify themselves as true Christian Churches.
Paul clearly explained the purpose of Spiritual Gifts. God gave Spiritual Gifts for the perfecting of the saints, for the work of the ministry, for the edifying of the Body of Christ: as we use our Spiritual Gifts, the Body of Christ will be edified, unified, and matured; we will avoid deception by Satan and by wicked men; and we will grow in Christ.
The other sacraments that Christ Himself instituted, are the 'Baptism' [Matthew 28:18–20]; [Mark 16:16], AND Holy Communion [Matthew 26:26–29].
Therefore, it is imperative that we choose the right Church. The best way is to ask God's guidance (through prayer) in this regard. Because apart from the Gospel preached, there is no Church. Period! And the Gospel includes the Gifts of the Spirit.
There are also difficult circumstances where people cannot attend a church, for example 'anti-Christian' countries-- where public gatherings are extremely difficult. God knows the circumstances.
Can we have fellowship and experience God outside the Church? Yes. What do you think we do during the week? We are the Church (body) and wherever we go Jesus goes with us.
