What is a day of judgment and peace in Catholicism?

In Catholicism, the Day of Judgment, also known as the Last Judgment, refers to the final judgment by God of all humanity at the end of time, when Christ will return to assess each person's life and faith. It is believed that the righteous will be rewarded with eternal life in heaven, while those who have rejected God will face eternal separation from Him. This day is often associated with the fulfillment of God's promise of justice and mercy. The concept of peace is linked to the hope of salvation and the restoration of creation, where God's kingdom will ultimately reign.
