An argument against a “religion” is a cop-out. At best, the person has a rhetorical idea of what religion is, despises it, and thus rejects it. We may very well also reject the idea of a group of people practicing cabalistic rituals without meaning - though we embrace Scripturally-founded liturgies that convey meaning symbolically as well as literally.
What I’ve often found is that those who dislike “religion” in the Catholic Church either want something entirely intellectual and rational that does not resemble anything mystical, or they don’t understand the meaning of the liturgy.
At worst, the person wishes to convey that they alone are the only authority they will follow - usually by saying “I obey Scripture” although Scripture is not an instruction manual and is often not clear.
Among things that are clear in Scripture are:
- Jesus’ assigning of authority to the Apostles, ie: Mt 16:18-20, Mt 18:18, Jn 20:21-23
- The hierarchical nature of the Church, following that authority, ie: Phil 1:1, Ti 1:7
- The sacraments: Ja 5:14-15, 1 Cor 10:16, 1 Cor 11:27, 1 Jn 1:9
Among things that are not spoken about in Scripture:
- That we are each to interpret Scripture for our own understanding
- That in 1611 the Bible was hidden until it fell from the sky in King James English, leather-bound and red-lined.
- That each believer in the Bible went about preaching his or her own understanding of Scripture in accord with being a “royal priesthood” (1 Pt 2:9)
How would you answer such a person? First, clarify the objection.
If they don’t like symbolism, then how do they explain Scripture that is full of hyperbole and metaphor?
If they don’t like the existence of an earthly authority other than the Bible, you could take them to task to explain the passages about Apostolic authority.
If they believe that the eucharist is merely symbolic, then how can it be received unworthily and thus render someone “guilty of the body and blood”?
If they believe that faith alone saves, then why are judged according to our deeds, and why is baptism, repentance, confession of Christ and obedience to his commands required for salvation?
