Local priest Father Ron Millican from nearby Our Lady of Sorrows parish and Rev. Elizabeth Larson from St Mark Lutheran Church came to show their support for Fr. Marquez, as well as Matt Cato, director of the Archdiocese of Portland's Office of Life, Justice and Peace.
Archbishop Alexander Sample expressed his support to St. Peter's through a letter to the parish, saying that he was saddened by the harassment and offering his prayers for healing.
"Please be assured that I, as your Archbishop and shepherd, stand firmly with you in the face of such ignorant and hateful words. You are our brothers and sisters, and as members of the same family of faith, we must hold fast to our unity in Christ," he said.
He added that the incident was not isolated and that the same group had been harassing other churches in the area. The men were reportedly part of a Portland-based group called "Bible Believers"-hard-right street preachers who appear at protests against President Donald Trump.
"Be assured of my love and prayers for all of you. May Our Lady embrace you all in her mantle of love and protection," Archbishop Sample concluded.
