Marcellus, Bishop of Ancyra, and his pupil Photinus, are anathematized in the Creed called Μακρόστιχος as holding that Christ first became “Son of God when He took our flesh from the Virgin.…For they will have it that then Christ began His Kingdom, and that it will have an end after the consummation of all and the judgment.  Such are the disciples of Marcellus and Scotinus of Galatian Ancyra, &c.”  See Newman on Athanasius, de Synodis, § 26, (5), notes a and b.  Compare the description of Marcellus in the Letter of the Oriental Bishops who had withdrawn from the Council of Sardica to Philippopolis (a.d. 344).  “There has arisen in our days a certain Marcellus of Galatia, the most execrable pest of all heretics, who with sacrilegious mind, and impious mouth, and wicked argument seeks to set bounds to the perpetual, eternal, and timeless kingdom of our Lord Christ, saying that He began to reign four hundred years since, and shall end at the dissolution of the present world” (Hilar. Pictav. Ex Opere Hist. Fragm. iii.).
