Most believe that First Clement was written from the church of Rome to the church in Corinth.
Keeping that in mind, go and scan 1Cor 13 quickly. Got it? Good.
Then read First Clement 49:
49. Let the one who has love in Christ fulfill the commandments of Christ.
(2) Who can describe the bond of God’s love?
(3) Who is able to explain the majesty of its beauty?
(4) The height to which love leads is indescribable.
(5) Love unites us with God; “love covers a multitude of sins”; love endures all things, is patient in all things. There is nothing coarse, nothing arrogant in love. Love knows nothing of schisms, love leads no rebellions, love does everything in harmony. In love all the elect of God were made perfect; without love nothing is pleasing to God.
(6) In love the master received us. Because of the love he had for us, Jesus Christ our Lord, in accordance with God’s will, gave his blood for us, and his flesh for our flesh, and his life for our lives.

49.1 Ὁ ἔχων ἀγάπην ἐν Χριστῷ ποιησάτω τὰ τοῦ Χριστοῦ παραγγέλματα.
(2) τὸν δεσμὸν τῆς ἀγάπης τοῦ θεοῦ τίς δύναται ἐξηγήσασθαι;
(3) τὸ μεγαλεῖον τῆς καλλονῆς αὐτοῦ τίς ἀρκετὸς ἐξειπεῖν;
(4) τὸ ὕψος εἰς ὃ ἀνάγει ἡ ἀγάπη ἀνεκδιήγητόν ἐστιν.
(5) ἀγάπη κολλᾷ ἡμᾶς τῷ θεῷ, ἀγάπη καλύπτει πλῆθος ἁμαρτιῶν, ἀγάπη πάντα ἀνέχεται, πάντα μακροθυμεῖ· οὐδὲν βάναυσον ἐν ἀγάπῃ, οὐδὲν ὑπερήφανον· ἀγάπη σχίσμα οὐκ ἔχει, ἀγάπη οὐ στασιάζει, ἀγάπη πάντα ποιεῖ ἐν ὁμονοίᾳ· ἐν τῇ ἀγάπῃ ἐτελειώθησαν πάντες οἱ ἐκλεκτοὶ τοῦ θεοῦ· δίχα ἀγάπης οὐδὲν εὐάρεστόν ἐστιν τῷ θεῷ.
(6) ἐν ἀγάπῃ προσελάβετο ἡμᾶς ὁ δεσπότης· διὰ τὴν ἀγάπην, ἣν ἔσχεν πρὸς ἡμᾶς, τὸ αἷμα αὐτοῦ ἔδωκεν ὑπὲρ ἡμῶν Ἰησοῦς Χριστὸς ὁ κύριος ἡμῶν ἐν θελήματι θεοῦ, καὶ τὴν σάρκα ὑπὲρ τῆς σαρκὸς ἡμῶν καὶ τὴν ψυχὴν ὑπὲρ τῶν ψυχῶν ἡμῶν.
