Doubt and Christian lifeDraft · awaiting advisor review

Which is the true church: Catholic, Orthodox or Protestant?

In short

Catholic, Orthodox and Protestant Christians each make a serious case, and all three confess the Nicene Creed: the Trinity, Christ fully God and fully man, and his bodily resurrection. Opened believes the Bible is the final authority for faith and life, as Protestants hold. Division among Christians is a wound Jesus prayed against, and no short answer settles it.

The Objection

Protestantism has split into countless groups because everyone reads the Bible for himself. The ancient churches have bishops, liturgy and continuity back to the apostles. Surely Jesus founded one visible church.

Put as its strongest advocates would put it.

The Christian Case

Historical evidence
The question is live again, especially among young men, some of whom are joining Orthodox and Catholic churches. Reports suggest real interest, though the numbers are small and hard to measure.
Scripture
Jesus prayed that his followers would be one, and Paul speaks of “one body… one Lord, one faith, one baptism”. Division among Christians is a wound, not something to celebrate.
Christians differ
Opened believes, as Protestants do, that Scripture is the final authority for Christian faith and conduct, above every tradition. Catholics point to Peter and the unbroken line of bishops in communion with Rome. Orthodox Christians point to unchanged worship and the ancient councils. Each tradition has a serious case.
Historical evidence
All three confess the Nicene Creed: the Trinity, the full divinity and humanity of Christ, and his bodily resurrection.

Where the Evidence Is Weaker

This is a genuine disagreement among informed, faithful Christians, and no short answer settles it. Each tradition’s argument depends on prior views about Scripture, tradition and authority.

Arguments to Avoid

Saying members of other traditions aren’t Christians.
Quoting the “40,000 denominations” figure as a measure of disagreement.
Presenting one tradition’s view as “the Christian view”.

John 17:20–23

²⁰Neither pray I for these alone, but for them also which shall believe on me through their word; ²¹That they all may be one; as thou, Father, art in me, and I in thee, that they also may be one in us: that the world may believe that thou hast sent me. ²²And the glory which thou gavest me I have given them; that they may be one, even as we are one: ²³I in them, and thou in me, that they may be made perfect in one; and that the world may know that thou hast sent me, and hast loved them, as thou hast loved me.

Ephesians 4:1–6

¹I therefore, the prisoner of the Lord, beseech you that ye walk worthy of the vocation wherewith ye are called, ²With all lowliness and meekness, with longsuffering, forbearing one another in love; ³Endeavouring to keep the unity of the Spirit in the bond of peace. ⁴There is one body, and one Spirit, even as ye are called in one hope of your calling; ⁵One Lord, one faith, one baptism, ⁶One God and Father of all, who is above all, and through all, and in you all.

Acts 17:10–12
