St. Apollinaris travelled to Rome with St. Peter, who ordained him and sent him to Ravenna to preach the Gospel there. Apollinaris was beaten mercilessly by the local pagan priests, and driven from the city. He continued to suffer terrible tortures as he continued to spread the Faith, but he remained faithful to Christ, giving his life as a martyr.
Almighty God, by whose grace and power thy holy martyr St. Apollinaris triumphed over suffering and was faithful even unto death: Grant to us, who now remember him with thanksgiving, to be so faithful in our witness to thee in this world, that we may receive with him the crown of life; through Jesus Christ our Lord, who liveth and reigneth with thee and the Holy Spirit, one God, for ever and ever. Amen.
