The Bishop of Gloucester has teamed up with pupils from All Saints' Academy in Cheltenham, to promote the message that who you are is more than your external appearance.
Bishop Rachel said: "So many young people today are sourcing their identities from social media and advertising and in the process losing their self-esteem, which is one of the reasons why our campaign is called #liedentity."
The Bishop of Gloucester went on: "So much of what they experience through social media presents a message of value based on physical appearance.
"I long for every young person to discover their worth as a unique individual created in the image of God and to find happiness as they go on becoming who they have been created to be.
"We need to start thinking about the messages we give out to others and how what we say, can shape how people see themselves. When we compliment others how often do we link it to physical appearance?
"For example, our opening comment in a conversation with a young girl is often about how pretty she looks."
This campaign is a new step by the Church, lead by the first female bishop to sit in the House of Lords.
Part of the campaign asks people what they want to change about themselves, that body part is then removed in a picture of them via Photoshop.
"The pictures are quite stark, but remind us that being Photoshopped does not create a realistic image," she said.
"I want people to feel happy inside out and delight in their whole self."
