Most Catholics conformed outwardly — they didn’t openly challenge Elizabeth or refuse attendance unless necessary.
Elizabeth herself helped preserve this situation:
Refused to administer second Oath of Supremacy, avoiding death penalties.
No one executed for saying Mass, despite it being illegal.
Lacked resources to crack down on widespread Catholicism, especially in the north.
Heavy - handed action could have caused political unrest.
Foreign diplomacy also influenced leniency:
Pope Pius IV (1559–65) believed England could return peacefully to Rome.
Spain urged the Pope not to intervene directly.
Turning point: Mary, Queen of Scots fled to England in 1568.
Her presence as a Catholic alternative to Elizabeth shifted the landscape, increasing concerns about Catholic loyalty.
