On Trinity Sunday many Lutheran churches confess their faith in the language of the Athanasian Creed as it is found on page 53 of TLH. The Athanasian Creed was named after St. Athanasius one of the church's most important teachers; and defenders of the Trinitarian faith. The Athanasian Creed is an official confession of the Lutheran Church.

This Creed was established over a period of about 50 years (325 AD to 371 AD). Using Sacred Scripture as its source it gave the church true language to speak about, and think about God. This was no small task, but one which took the church more than three centuries. This Creed was further explained by the teaching of the Cappadocian Fathers: Sts. Basil, Gregory of Nyssa, and Gregory of Nazianzus. Their writings, again based on Sacred Scripture, and the Athanasian Creed, are the foundation of the church's doctrine of God, with a focus on the doctrine of the Person and Work of our Lord Jesus Christ. We are the heirs of their great labor and pains! We have much for which to be thankful this Trinity Sunday. Whether you are young or old there is no more satisfying, or edifying study in which a person can engage than in the history, doctrine, worship and practice of the holy Christian church. Such study is conducted every Sunday morning at 9 AM. Jesus says, "What does it benefit a man if he gain the whole world, but lose his own soul." To make the study of sacred things your priority is to: lose the whole world, but to gain your soul.
