mid then this church physical or only spiritual?
The Body of Christ is Both Physical and Spiritual. Jesus is the Word of God, the Christian in the Body has the word of God as written and has the Holy Spirit as teacher, who opens the word of God to them and gives them wisdom and understanding, the essential doctrines of the faith are all in the word of God, hence the "sola scriptura" But on top of this is Holy Spirit revelations, which will never contradict the word of God, Only reinforce and add depth of meaning to the words therein. This divine revelation is not just granted to select leaders but to all parts of the body receive Truth, so your Baptists have truth, and your Calvinists have some and Catholics have some, and the charismatics have some, for as Paul said, we all know in part until that perfect has come in.
For we know in part, and we prophesy in part. But when that which is perfect is come, then that which is in part shall be done away. (1 Corinthians 13:9-10)
That "perfect is come" is when we as Christians are filled with the fulness of Christ, which comes with the unity of the Spirit, which comes with all the parts of the body in fellowship and Agape love for one another.
This is the final transformation when the fulness of the gentiles comes in, the church age will end and the age of the saints will begin, which is what Revelation speaks of.... But that is a different topic.
