In 2018, the Sejm adopted the act establishing the National Day of Remembrance for Steadfast Clergy. It is celebrated on 19 October as a public holiday passed in tribute to "heroes, steadfast defenders of faith and independent Poland."

The date of their commemoration was chosen on 19 October as on that day in 1984, Security officers abducted Father Jerzy Popiełuszko, whom they later cruelly tortured and murdered.
