Pope Francis is known for taking time to bless the vulnerable: children, the sick and the disabled.

Isabella “Bella” Santorum, the seven-year-old daughter of Republican presidential candidate Rick Santorum, was no exception over the weekend. Born with a genetic disorder known as Trisomy 18, Bella was with family members in Philadelphia when she received a special blessing from Pope Francis.

The moment was captured on camera and made public on Instagram and Twitter. “He carried Bella up in his arms, kissed her, and blessed her. Tears of joy all around for the blessing of this holy and precious Father!” wrote Elizabeth Santorum, one of the Santorums’ seven children.

“When he speaks in interviews, he’s giving his own opinions, which I certainly will listen to,” Santorum said. “But from my perspective, that doesn’t reflect the idea that people shouldn’t be fruitful and multiply, and that people should be open to life as something that is a core value of the faith and of the Catholic church.”

Francis departed Philadelphia for Rome on Sunday after spending six days in the United States. His official account tweeted this early Monday:
