A church bell is rung to signify the hour or the time for worshippers to stop and pray. In many Catholic churches, the ringing of a church bell for the Angelus prayer, morning, midday and evening, is called the Angelus bell.
Morning, noon and evening bells were influenced by the Jewish practice of praying to the Lord three times a day. This practice is found in the Old Testament; for example in Psalm 55:17, which suggests "praying, morning, noon and evening," and in Daniel 6:10 (Daniel prayed three times a day).
Evening bells are still a common way for all the faithful to stop their busy lives for a moment to say a prayer, and remember the thought of Isaiah: “Be still, and know that I am God.”
“Whoever believes in me believes not in me, but in him who sent me. And whoever sees me sees him who sent me. I have come as light into the world, so that everyone who believes in me should not remain in the darkness…” (Jn 12: 44)
