Greek Orthodox Church commemorates saints Bartholomew, Barnabas and others on June 11

The Greek Orthodox calendar marks June 11 as the feast day of several early Christian figures. The Church honors the apostles Bartholomew and Barnabas, both noted for missionary work in India, the Middle East and Cyprus and for martyrdom at the hands of hostile authorities. It also commemorates Saint Luke, Archbishop of Simferopol‑Crimea, a 20th‑century surgeon‑bishop who suffered persecution under Soviet rule, and New Martyr Zephyr, who was executed during Ottoman oppression.

A related entry for June 12 notes the remembrance of Saint Onuphrius of Egypt, an influential 4th‑century ascetic, and highlights the International Day Against Child Labour, observed worldwide to raise awareness of child exploitation.

These entries provide brief biographical sketches of the saints and note the broader cultural observances linked to the dates.
