From the Presbyterian Church (USA) website:
Well Chosen Words, a guide to understanding and using inclusive language, was developed by the Racial Ethnic and Women’s Ministries/Presbyterian Women's ministry area in consultation with the Advocacy Committee on Women’s Concerns. Its cites Galatians 3:27-28 in which Paul asserts, “As many of you as were baptized into Christ have clothed yourself with Christ ... for all of you are one in Christ Jesus.” Inclusive language allows all God’s children to be one in Christ Jesus.
The guide encourages language choices that proclaim the fullness of God, outlining traditional depictions as well as newer images to describe God, Jesus and the Holy Spirit.
What is inclusive language?
The way you phrase a message is often as important as the message itself. The practice of using inclusive language is something more than remembering a list of grammatical and stylistic "things to avoid"-it is a commitment to thoughtfully choose words that will make all people feel welcomed. We want to include not exclude.
Why bother to avoid gender-specific language?
Traditionally, writers in the English language have used masculine identifiers and pronouns to address the idea of the "Universal Singular"-terms like "mankind," "men of faith" "Master"-and so on. For centuries, the patriarchal system of English and American society was reinforced by the use of the pronoun referent "he." Because of the use of masculine language, women were, in the main, considered less than men or simply not considered at all. Our language shapes our culture-and to be systematically denied recognition has a rather disenfranchising effect on women.
The minister of a local church once said, "We need to elect a property chairman so that he can get the church's roof fixed!" Only men can chair committees? Are males the only gender capable of picking up the phone and contacting a roofer?
How can you avoid using gender-specific language?
First, recognize that your inclination to write in the masculine doesn't make you a creep. Most likely, it is the language of your younger years and may be most familiar and comfortable to you. Focus on getting your main ideas down on paper in the brainstorming and early drafting stages of your writing process, saving inclusive language issues for your revision time so that you don't forget your salient points.
