For the Strength of Youth, a source of clear and direct outlines of basic Church standards, underwent a revision process this last year, and the booklets are being distributed to wards and branches throughout the Church. I love this book. It's designed to help Church members create habits in living the standards that will guide them throughout their lives.
There is no double standard in the Church. The standards apply universally to youth, adults, and all other members. That's why they're called "standards" and not "youthful suggestions."
The new booklet covers issues that weren't present during the last revision in 2001 - things like mobile devices - and clarifies other issues. There's a section on emotional health that talks about depression, a new section on education, and some other cool features. The pdf or printed booklet itself has more text than the resources available online at standards.lds.org.
There's a paragraph on same-gender attraction, but the section that really spoke to me when I read it this morning was on agency and accountability. I'll include some of the last paragraph here.
Some sinful behavior may bring temporary, worldly pleasure, but such choices delay your progress and lead to heartache and misery. Righteous choices lead to lasting happiness and eternal life. Remember, true freedom comes from using your agency to choose obedience; loss of freedom comes from choosing disobedience.
That's true. When I find myself faced with the choice of following pleasure or pursuing lasting happiness, the only way to find peace is to follow God. He has given me all the tools to be happy, if I will follow Him and keep His commandments.
