Apostle Thaddeus of the Seventy; Avram, Archimandrite of Smolensk; Holy Martyrs Bassa and her sons Theognis, Agapios, and Pistis (4th c.)

Now, brethren, if I come unto you speaking with tongues, what shall I profit you, except I shall speak to you either by revelation, or by knowledge, or by prophesying, or by doctrine? ⁷And even things without life giving sound, whether pipe or harp, except they give a distinction in the sounds, how shall it be known what is piped or harped? ⁸For if the trumpet give an uncertain sound, who shall prepare himself to the battle? ⁹So likewise ye, except ye utter by the tongue words easy to be understood, how shall it be known what is spoken? for ye shall speak into the air. ¹⁰There are, it may be, so many kinds of voices in the world, and none of them is without signification. ¹¹Therefore if I know not the meaning of the voice, I shall be unto him that speaketh a barbarian, and he that speaketh shall be a barbarian unto me. ¹²Even so ye, forasmuch as ye are zealous of spiritual gifts, seek that ye may excel to the edifying of the church. ¹³Wherefore let him that speaketh in an unknown tongue pray that he may interpret. ¹⁴For if I pray in an unknown tongue, my spirit prayeth, but my understanding is unfruitful. ¹⁵What is it then? I will pray with the spirit, and I will pray with the understanding also: I will sing with the spirit, and I will sing with the understanding also. ¹⁶Else when thou shalt bless with the spirit, how shall he that occupieth the room of the unlearned say Amen at thy giving of thanks, seeing he understandeth not what thou sayest? ¹⁷For thou verily givest thanks well, but the other is not edified. ¹⁸I thank my God, I speak with tongues more than ye all: ¹⁹Yet in the church I had rather speak five words with my understanding, that by my voice I might teach others also, than ten thousand words in an unknown tongue.

And he goeth up into a mountain, and calleth unto him whom he would: and they came unto him. ¹⁴And he ordained twelve, that they should be with him, and that he might send them forth to preach, ¹⁵And to have power to heal sicknesses, and to cast out devils: ¹⁶And Simon he surnamed Peter; ¹⁷And James the son of Zebedee, and John the brother of James; and he surnamed them Boanerges, which is, The sons of thunder: ¹⁸And Andrew, and Philip, and Bartholomew, and Matthew, and Thomas, and James the son of Alphaeus, and Thaddaeus, and Simon the Canaanite, ¹⁹And Judas Iscariot, which also betrayed him: and they went into an house. ²⁰And the multitude cometh together again, so that they could not so much as eat bread. ²¹And when his friends heard of it, they went out to lay hold on him: for they said, He is beside himself.
