Apolytikion in the Plagal of the First Tone
He that thundered on Sinai with saving laws for man hath also given thy writings as guides in prayer unto monks, O revealer of unfathomable mysteries; for having gone up in the mount of the vision of the Lord, thou wast shown the many mansions. Wherefore, O God-bearing Isaac, entreat the Saviour for all praising thee.
Kontakion in the Plagal of the Fourth Tone
As an ascetic and God-bearer great in righteousness and an instructor of monastics do we honour thee, thou revealer of things sacred, and our protector. But, O Isaac, since thou hast great boldness with the Lord, intercede with Him for all of us who sing thy praise and who cry to thee: Rejoice, O Father most wise in God.
