one who prays

From LSJ

μή, φίλα ψυχά, βίον ἀθάνατον σπεῦδε, τὰν δ' ἔμπρακτον ἄντλει μαχανάν → Oh! my soul do not aspire to eternal life, but exhaust the limits of the possible. | Do not yearn, O my soul, for immortal life! Use to the utmost the skill that is yours. | Do not, my soul, strive for the life of the immortals, but exhaust the practical means at your disposal.

The Euchites or Messalians were a Christian sect from Mesopotamia that spread to Asia Minor (modern-day Turkey) and Thrace. The name 'Messalian' comes from the Syriac ܡܨܠܝܢܐ, mṣallyānā, meaning 'one who prays'. The Greek translation is εὐχίτης, euchitēs, meaning the same.
