People are being sent mobile phone text messages to encourage them to do good deeds and be more caring.
Right Rev Fletcher believes the church should use technology
A text hotline, set up by the Diocese of Oxford for Lent, urges people to do something helpful rather than just give something up like chocolate.
Users who text "Lent" to the number are sent suggestions everyday such as "give up your place to someone in a traffic jam or a queue".
The diocese of Oxford covers Berkshire, Oxfordshire and Buckinghamshire.
The Right Rev Colin Fletcher, acting Bishop of Oxford, told BBC News: "What the church has always done, from the earliest times, is use the media that is around - when printing came along the church was right in the forefront at getting the books out and using them.
"Here we have texting and that's very much part of our modern age."
The service will start on the 19 February, and mobile phone users can text 64343.
The texts cost 10p per day.
