Under the influence of relativism, many reject the Church’s authority. 'What’s true for you isn’t true for me'. Nobody knows what the truth is. 'Just do what feels good to you, right'?
Many are influenced by what Pope Benedict XVI calls ‘the Dictatorship of Relativism’ where all truth is relative, we each decide what is ‘true for me’, thereby making ourselves the arbiter of all truth. St. Paul describes this: “…having itching ears they will accumulate for themselves teachers to suit their own likings, and will turn away from listening to the truth and wander into myths” (2 Tim 4:3-4 RSV). The Church is viewed by many to be an outdated institution. “We need to get with the times.” But truth is not determined by a majority vote. Amen!?
Truth is a person. It has a name, Jesus Christ, "I am the Way, the Truth and the Life" (John 14: 6).
By submitting to that truth, the revealed truth from God, we can have clarity about what is right and what is wrong, what to believe and what is false teaching. ‘Cafeteria Catholicism’ is quite popular: “...there is a tendency on the part of some Catholics to be selective in their adherence to the Church’s moral teachings. It is sometimes claimed that dissent from the Magisterium is totally compatible with being a ‘good Catholic’... This is a grave error” (John Paul II, Address to US Bishops, 16 Sep 1987, 5).
I think we all need to hear this. We need to hear that you cannot be a good Catholic and select what to believe about Church teaching, especially when it is defined definitively or infallible.
