We in the Church of England, do not pray to the saints in heaven. We believe we have direct access to The Father, through Christ. However, when I lead intercessions for the church on a 3rd Sunday in the month, I conclude them with this statement or something similar. "Now with St Andrew, St Mary, (+ whatever is the nearest saints day), and all the saints in heaven and on earth we here ask these things in the name of Jesus Christ Our Saviour, Amen". .
