Tim Challies thinks Trevin Wax is sensibly moderate about observing Lent:
This much is beyond dispute: Nowhere in the Bible are we commanded to observe Ash Wednesday, Lent, Good Friday, Easter, or any other holy day. Nowhere are we forbidden. For that reason, these are holidays that some Christians may choose to observe while others may choose not to, and both are free to do so according to desire and conscience. “One person esteems one day as better than another, while another esteems all days alike. Each one should be fully convinced in his own mind,” says Paul (Romans 14:5). If it’s your conviction that observing these days is consistent with the Bible, then by all means do so. If it’s your conviction that observing them is inconsistent with the Bible, then by all means refrain. And as you celebrate or refrain, be careful not to judge or condemn those who choose the opposite. (You couldn’t go wrong reading Romans 14 this time of year.)
I believe Trevin Wax does a good job of cautioning both camps. To his friends who observe Lent he cautions “to not give off the impression that their brothers and sisters who refrain are ‘missing out,’” since if the practice was that beneficial to spiritual growth, God’s Word would have commanded it. He also warns against inadvertently offending “a weaker brother who found their former Catholicism or Anglicanism or whatever high-church tradition they were a part of to be life-draining, rather than life-giving.” Those who observe these days have a loving responsibility toward those who do not. To his friends who do not observe Lent he cautions “don’t impugn the motives of those who have found spiritual benefit in setting aside a time of the year for reflection on Christ’s passion.” I appreciate Wax’s concern and wisdom. Again this is Romans 14 stuff—basic, not advanced, Christianity.
Of course, part of the problem is that Lent used to be more like what Judaizers promoted — a sin that could keep you from heaven. As Philip Jenkins reminds those who practice Lent-lite:
To see just what Lent meant in earlier times – between about 500 and 1600 – we can also look at some ancient churches around the world, like in Christian Ethiopia: “This fast follows the old law, for they do not eat at midday, and when the sun is setting they go to church and confess and communicate and then go to supper.” Even when allowed to eat, “they eat nothing that has suffered death, nor milk, nor cheese, nor eggs, nor butter, nor honey, nor drink wine. Thus during the fast days they eat only bread of millet, wheat and pulse, all mixed together, spinach and herbs cooked with oil.” A Western observer noted that “The severity of their fasts is equal to that of the primitive church. In Lent they never eat till after sunset.” They kept that up for forty tough days.
In medieval times, European Christians also behaved much like that. Some accounts suggest that, especially in Holy Week, Christians were expected to get by on two or three meals in the entire week, never mind in any given day.
Imagine Paul saying, “don’t impugn the motives of the Judaizers,” just use your discernment about additions to the simplicity of trusting Christ alone.
At the same time, why is Challies generally of the conviction that Christians should not watch television shows and movies that include sexual content? How do you recommend moderation for the liturgical calendar but draw clear lines for artistic productions that contain sinful situations?
