Dietrich Bonhoeffer said the following.
Let him who cannot be alone beware of community. He will only do harm to himself and to the community. Alone you stood before God when He called you; alone you had to answer that call; alone you had to struggle and pray; and alone you will die and give an account to God. You cannot escape yourself; for God has singled you out. If you refuse to be alone, you are rejecting Christ’s call to you, and you can have no part in the community of those who are called….
Let him who is not in community beware of being alone. Into the community you were called — the call was not meant for you alone; in the community of the called you bear your cross, you struggle, you pray. You are not alone even in death, and on the Last Day you will be only one of the great congregation of Jesus Christ. If you scorn the fellowship of the brethren, you reject the call of Jesus Christ.
