Canon 32
About the prohibition of accepting blessed bread or pieces of prosphora from heretics.
About the fact that one should not accept blessings (εὐλογίας) from heretics, because this is rather vanity (ἀλογίαι) than blessings.
Greek original
Ὅτι οὐ δεῖ αἱρετικῶν εὐλογίας λαμβάνειν, αἵτινές εἰσιν ἀλογίαι μᾶλλον, ἢ εὐλογίαι.
