You better believe it. In 2015, the PC(USA) changed its constitutional language to state:
Marriage is a gift God has given to all humankind for the wellbeing of the entire human family… In civil law, marriage is a contract that recognizes the rights and obligations of the married couple in society. In the Reformed tradition, marriage is also a covenant in which God has an active part, and which the community of faith publicly witnesses and acknowledges.
Well before that, for decades in fact, Davis Community Church has been an ally and advocate with the LGBTQ community, even when it was not popular nor “acceptable” in our denomination. We regularly march in the Sacramento Gay Pride Parade and host support groups like Yolo Rainbow Families and the Phoenix Coalition.
The PC(USA) has over 175 years of experience and partner with churches in over 100 countries. We have a great theology of mission: Mission is not something Presbyterians “do to people,” but an adventure we do with God and with global partners around the world. Presbyterian mission co-workers are teachers, doctors, public health specialists, chaplains and human rights advocates. They teach theology, church history, Greek, Hebrew and English.
The PC(USA) is recognized worldwide for its success in volunteer training. Programs such as Presbyterian Disaster Assistance, the emergency and refugee program of the PC(USA), the Young Adult Volunteer program and the Self-Development of People program are but two examples of our ongoing commitment to human flourishing.
“Presbyterians are not do-it-yourselfers. We make decisions as a community. This is a way of living out the Biblical notion that God has created a covenant community. We base our decisions on our traditional sources of authority and guidance — the Bible and the church’s constitution. We pray and seek the guidance of the Holy Spirit in interpreting these sources of authority. We listen to each other, believing that God speaks in the community of the church.
Presbyterian polity is representative government, very similar to the United States government. Authority flows both up and down. We elect representatives to make decisions on our behalf.
One difference in emphasis between our national and church governments is that the persons Presbyterians elect to represent them are expected to vote according to their consciences as they are informed by the Holy Spirit.
Our representative form of government puts significant responsibility on all members of the church. We are continually called upon to decide whom we should elect and what side of multiple issues we should support.
The Presbyterian way of making decisions looks a lot like the way the New Testament church made decisions as recorded in Acts 15:1-21.”
