Post-Christian Era: Understanding the Shift Away from Biblical Foundations in Modern Society

Explore the profound transformation of Western culture as traditional Christian values give way to secular worldviews. This article examines the characteristics, dangers, and spiritual implications of living in a post-Christian society while calling believers to faithful witness and personal examination.

The Decline of Christian Influence in Western Culture

The Christian values and their expression that once permeated, flourished and influenced Western culture are now being replaced by the worldviews of secularism, atheism and environmentalism. In ignorance and self-deception modern society considers it knows better than our spiritual predecessors and consequently has adopted an ungodly perspective (Rom 1:22-31). Such an outlook is termed post-Christian and is empowered by post-modernism that elevates self, experience and opinion above fact and reason.

Yet even when "enlightened" society allegedly moves on, God's standards remain unchanged from the beginning of time, reinforced in the Christian age through the ministry of Jesus and the apostles' teaching as recorded in the Bible. What was morally true in Eden, declared through the Law and the Prophets, and confirmed by Christ and His apostles does not shift with cultural trends or majority opinion.

Decreasing biblical literacy has resulted in the erosion of people's reliance on and adherence to Christian principles. Although some Christian customs and ideas will be retained their Christian origins will not be acknowledged and they will be disguised under different names and explanations.

The Challenge to Biblical Authority Within the Church

Even in the church its previous Bible foundational roots are being challenged and increasingly rejected in favour of liberal reform and theology including the 'cheap gospel' which says while a person may acknowledge Christ, His teachings don't necessarily have to be followed (2 Tim 4:3). The authority of God and allegiance to His Word is replaced with whatever seems acceptable to each person, being influenced by peer pressure, opinion and the prevailing mind-set of the secular world which is opposed to God (Jdg 17:6; Mk 7:8).

The central idea that is replacing Christianity is the idea that man can save himself, or even, that he needs no saviour other than himself. A saviour or redeemer implies the existence of something he cannot achieve by himself.

Individuals and societies that ignore His truth, believing in pluralism that there are multiple paths to 'God', whoever or whatever they perceive that to be, will end in disaster having relied on a faulty foundation (Mt 7:26-27). The Bible is clear, Jesus is the exclusive way to the only true God (Isa 43:11, 44:6, 45:21; Jn 14:6; Act 4:12). Having a mental understanding of Christianity will not save a person – there must be a heart relationship with Christ, which will be outworked in a changed lifestyle.

Moving away from Christ always ends badly

The Consequences of Rejecting God's Truth

Increasingly mankind formulates their own spirituality, and with the range of diverse opinions even calling good evil and evil good a robust discussion would disturb the peace and could be classed as hate speech (Isa 5:20). Even those who have tried to ignore or say God doesn't exist will give account to Him (Rom 14:12; Heb 9:27). As this will be according to His rules – Jesus and the Words He spoke and not our ideas or opinions it makes sense to live by His conditions to avoid condemnation and eternal regret (Jn 5:22,27, 12:47-48; Act 10:42, 17:31; 2 Thes 1:8; Heb 4:12-13; 1 Pet 4:17).

Satan has blinded the minds of unbelievers to the fact that they are lost and in need of a Saviour. Instead, they feel lonely and hopeless, considering self-indulgence through consumerism and pleasure with self-discovery to be the answer to their inner feeling of discontent because they are not connected to the real source of life (Jn 10:10; 2 Cor 4:4). The Bible speaks of people in the last days being lovers of self and all manner of ungodly behaviour (2 Tim 3:1-4). Modern day believers have, as a whole, failed appallingly to give a valid portrayal of the genuine life transformation possible in Christ – this is in complete contrast to the early Christians who made a substantial impact in their communities because they could not refrain from speaking about the wonderful things Jesus said and did (Mk 16:20; Act 4:20, 17:6).

All who identify as Christians are encouraged to carefully consider the basis of their faith. Scripture warns that many people may be left out of heaven, not because they lack religious practice, but because their commitment is to a system rather than to the person of Jesus Christ and obedience to the Word of God (Mt 7:21-23). God’s promise remains: "Walk in all the ways I command you, that it may go well with you" (Jer 7:23). Genuine faith is evidenced by living in accordance with God's commands, not merely by religious association.

Are my beliefs and faith anchored in the truth of God's Word?

As Paul exhorts, "Examine yourselves to see whether you are in the faith; test yourselves. Do you not realise that Christ Jesus is in you — unless, of course, you fail the test?" (2 Cor 13:5). This process of self-examination is not intended to foster uncertainty or doubt, but rather to encourage believers to walk confidently in the truth, continuously ensuring that their lives reflect the One they profess to follow.

Reflection and Application:

Examine your own faith foundation – are you following religious traditions or in genuine relationship with Jesus Christ?
Consider how post-Christian thinking may have subtly influenced your own worldview and values.
Reflect on your responsibility as a believer to clearly communicate the transformative power of the gospel in your community.
Identify practical ways to deepen your biblical literacy and resist the erosion of Christian truth in daily life.
