That the Son became man in this manner: he was conceived by the Holy Spirit without the cooperation of man and was born of the pure, holy, and virgin Mary.
The Smalcald Articles were written in Latin and in German, and the bolded words in the Latin text are rendered "ever-Virgin Mary". Regretably, most English translations are based on the German text.
A very appropriate discussion for this feast-day of the Presentation of Our Lord and the Purification of the Blessed Virgin Mary.
Apolytikion in the First Tone
Hail Virgin Theotokos full of Grace, for Christ our God, the Sun of Righteousness, has dawned from you, granting light to those in darkness. And you, O Righteous Elder, rejoice, taking in your arms, the Deliverance of our souls, who grants us Resurrection.
Kontakion in the First Tone
Your birth sanctified a Virgin's womb and properly blessed the hands of Symeon. Having now come and saved us O Christ our God, give peace to Your commonwealth in troubled times and strengthen those in authority, whom You love, as only the loving One.
When the most pure Mother and Ever-Virgin Mary's forty days of purification had been fulfilled, she took her first-born Son to Jerusalem on this, the fortieth day after His birth, that she might present Him in the temple according to the Law of Moses, which teaches that every first-born male child be dedicated to God, and also that she might offer the sacrifice of a pair of turtle-doves or two young pigeons, as required by the Law (Luke 2:22-24; Exod. 13:2; Lev. 12:6-8). On this same day, a just and devout man, the greatly aged Symeon, was also present in the temple, being guided by the Holy Spirit. For a long time, this man had been awaiting the salvation of God, and he had been informed by divine revelation that he would not die until he beheld the Lord's Christ. Thus, when he beheld Him at that time and took Him up into his aged arms, he gave glory to God, singing: "Now lettest Thou Thy servant depart in peace, O Master. . ." And he confessed that he would close his eyes joyfully, since he had seen the Light of revelation for the nations and the Glory of Israel (Luke 2:25-32). From ancient times, the Holy Church has retained this tradition of the churching of the mother and new-born child on the fortieth day and of the reading of prayers of purification.
