The line is a fragment of a prayer by Benedictine sister Mary Lou Kownacki — “Engrave this upon my heart: There isn’t anyone you couldn’t love once you’ve heard their story.” Fred Rogers carried a copy of it and loved to share it, which is how it drifted onto his name, but per Quote Investigator the words are Kownacki’s, first documented in 1994.
“There isn't anyone you couldn't love once you've heard their story” Mary Lou Kownacki, OSB — first documented in More Random Acts of Kindness (Conari Press, 1994); later carried and popularized by Fred Rogers. Often misattributed to Mister Rogers.

Engrave this upon my heart: There isn’t anyone you couldn’t love once you’ve heard their story.
The famous line is the second half of Kownacki’s prayer; a separate 2003 compilation, Worth Repeating, swapped “my” for “thy” in the opening clause.
The definitive trace is Quote Investigator’s 2022 entry, which finds the earliest strong match in the 1994 anthology More Random Acts of Kindness, attributing it to Mary Lou Kownacki, OSB.
In The World According to Mister Rogers (2003), the saying appears with a note that Fred Rogers “loved especially — and carried around with him” this quote by Kownacki, per his wife Joanne’s framing.
Mary Lou Kownacki (1941–2023) was a Benedictine sister of Erie, poet, and peace activist — long a writing partner and “muse” to Sister Joan Chittister.
The wording is a modern composition, first documented in 1994’s More Random Acts of Kindness (Conari Press) and reprinted in The World According to Mister Rogers (2003); as a post-1930 work by an identifiable author it remains under U.S. copyright.

How it became a “Mister Rogers” quote
Fred Rogers admired this line so much that he carried it with him and quoted it — and because his name is one of the internet’s biggest magnets for feel-good sayings, the words were gradually reassigned to him.

✓The words are Mary Lou Kownacki’s, first documented in 1994; Rogers carried and popularized them, and his wife Joanne credited Kownacki in the 2003 foreword to The World According to Mister Rogers, per Quote Investigator.
Context
Why it resonated
The sentence works as a compact plea for empathy: it argues that understanding someone’s history dissolves the distance that makes them easy to dislike. Kownacki wrote it as a prayer — a thing to engrave on the heart — which is why it reads as a moral discipline rather than a slogan.
Fred Rogers, whose whole vocation was helping children see the humanity in others, found it irresistible and carried it with him. His endorsement gave the line a second life and, ironically, a second author.
There isn’t anyone you couldn’t love once you’ve heard their story.
