Yes! I ask only that you do so within these rules of Creative Commons copyright :
You attribute me when you use them. That is, you note that I made them and that I am the copyright holder. You can do this easily by printing the phrase "copyright 2018 Emily J. Garcia."
You do not use them for profit. That is, you cannot print them off and sell them, or make money from my work in any way (in the same way that I am not making any money from them).
If you use them and adapt them (hooray!), you must make them available under the same kind of copyright. That is, you cannot make money off of that, or restrict other people from using your adapted liturgy.
This is a good question!
First, what I have made is available for free. That's why it's all on this website for everyone to see and use. Too many of the thoughtful resources developed in our tradition are expensive (like the Godly Play books and the national church's resources). A notable exception is the Center for the Ministry of Teaching's free magazine, The Episcopal Teacher.
Second, attribution is important to me because I think a person should be recognized for the work they do (1 Timothy 5:18, Luke 10:7). This means a person who says something funny or thoughtful should be mentioned when you say the funny or thoughtful thing again; a person who took a good picture should get credit when you #repost it; a person who came up with an idea that you liked and adapted should be cited when you share that idea again. I care about this in all parts of my life, because it is a gesture that keeps us grateful and humble, shows the heritage of an idea, and shows how we are dependent upon each other.
Third, these other rules are in place because I don't want someone else to make money off of a thing that I purposefully made to be free. Lack of money shouldn't stop ideas from getting around.
