Families tend to share everything — and this can have both positive and negative effects. When one of the kids gets the flu, for example, sure enough, everyone in the family is soon down with it.
This same principle can sometimes be found in the spiritual life of a family, and in a positive sense. If one person displays extraordinary sanctity, there is a higher chance that a sibling (or even a parent) will “catch” the “holiness bug.”
Throughout history the Church has recognized numerous family members who followed in their relative’s footsteps on that path of sanctity. This includes both siblings as well as married couples, such as Blessed Charles and his wife Zita or Saints Louis and Zelie Martin.
Of course four of the 12 Apostles are sibling pairs: Peter and Andrew are brothers, and James and John are brothers. So there’s precedent from the very start of the Church.
Here are five examples of siblings who learned from each other how to be holy.

Sts. Martha, Mary, and Lazarus
We read in the Gospel of Luke how Jesus “entered a village where a woman whose name was Martha welcomed him. She had a sister named Mary [who] sat beside the Lord at his feet listening to him speak” (Luke 10:38-39). The two, along with their brother Lazarus, were good friends with Jesus and have been regarded as saints since the early Church.
Sts. Benedict and Scholastica
The twins Benedict and Scholastica were attracted to the religious life at an early age and would go on to found the male and female branches of the Benedictine order. The two, while living separately in religious life, would visit with each other once a year, delighting in their talk of spiritual matters.
Sts. Macrina, Basil, Gregory, Peter and Naucratius
Macrina (the Younger) was born in the 4th century and was devoted to an ascetic life, becoming a nun after turning down a betrothal. Her brothers, Basil of Caesarea and Gregory of Nyssa, were influenced by her sanctity and pursued the religious life as well. Two other brothers, Peter of Sebaste and Naucratius, also sought to devote themselves to the Lord and were known for their holiness.
