July 3 is the date of the feast of St. Irenaeus in the traditional calendar. Renowned for his refutations of Gnosticism, he exemplified the exhortation of the Apostle Paul at a time — not unlike our own — foreshadowed in the latter’s second letter to Timothy (4.3-5):
Erit enim tempus, cum sanam doctrínam non sustinébunt, sed ad sua desidéria coacervábunt sibi magístros, pruriéntes áuribus, et a veritáte quidem audítum avértent, ad fábulas autem converténtur. Tu vero vígila, in ómnibus labóra, opus fac Evangelístæ, ministérium tuum ímpie.
For there will come a time when they will not endure the sound doctrine; but having itching ears, will heap up to themselves teachers according to their own lusts, and they will turn away their hearing from the truth and turn aside rather to fables. But be watchful in all things, bear with tribulation patiently, work as a preacher of the Gospel, fulfill your ministry.
The Secret Prayer of the Mass of the Feast of St. Irenaeus:
Deus, qui credéntes in te pópulos nullis sinis cóncuti terróribus: dignáre preces et hóstias dicátæ tibi plebis suscípere; ut pax, a tua pietáte concéssa, christianórum fines ab omni hoste fáciat esse secúros. Per Dominum nostrum Iesum Christum, Filium tuum: qui tecum vivit et regnat in unitate Spiritus Sancti Deus, per omnia saecula saeculorum. Amen.
O God, Who do not allow the nations that believe in You to be troubled by any distress, graciously accept the prayers and sacrificial gifts Your people dedicate to You, so that the peace bestowed by Your love may make Christian lands safe from every foe. Through Jesus Christ, thy Son our Lord, Who liveth and reigneth with thee, in the unity of the Holy Ghost, ever one God, world without end. Amen.
