Collect
Lord God
by your grace the apostle Saint Andrew
obeyed the call of your Son Jesus Christ
and followed him without delay;
grant that we may offer ourselves to you
in joyful obedience;
through Jesus Christ our Lord.
Amen.
Andrew was a follower of St John the Baptist, and according to the Gospel of John, the first of the apostles to be called by Jesus. He is mentioned several times in the Gospels; and because in three incidents he brings other people to Christ, St Andrews tide is often observed as a special time of intercession for mission. He has also long been regarded as the patron saint of Scotland. – Sourced from Saints and Seasons – Anglican Church of Southern Africa.
