Understand Catholicism
Plain answers, with the sources shown.
Written for someone starting from nothing, and for someone who was taught a harsh version of this and wants to check what the Church actually says.
We cite the Catechism and Church documents by paragraph, and we never invent a teaching. Church texts are quoted as published; the explanation and synthesis around them are our own.

Chapter one
Catholic social teaching
It begins with Christ's own words: what is done to the hungry, the thirsty, the stranger, the unclothed, the sick, and the imprisoned is done to him.
From that follow the principles: human dignity that is never earned, the common good, solidarity across borders and classes, subsidiarity, preferential concern for the poor and vulnerable, rights and their corresponding responsibilities, the dignity of work, and care for creation. They are worked out in a century of documents from Rerum Novarum to Fratelli Tutti, and they belong to no political party.
The corporal and spiritual works of mercy are how the principles stop being an argument: feed, give drink, clothe, shelter, visit the sick, visit the imprisoned, bury the dead; counsel, instruct, admonish, comfort, forgive, bear wrongs, pray.
