The Christian group said in a statement that it seeks "something of God in everyone and that leads them to work for justice for all".
It said their "commitment to truth, peace, equality and simplicity leads to five priorities: climate crisis, migration, criminal justice, peace and disarmament, and the nature of the debate".
Quakers in Britain said it is a time to influence future decision-makers.

The group has also mandated the language used by politicians is fair.
"Quakers are concerned by the violent language being used in the political arena," it said in a statement.
"They call on everyone involved... to listen to each other, seek the truth and seek common ground from which to move forward.
