Christ's Dwelling

In interiore homine Christum habitare per fidem in cordibus vestris. In eo petit eos magis firmari, ut non ambigant, sed magis credant Christum habitare in se, quem non vident his oculis; ut Spiritus datus hoc eis per Dei donum infundat, ut certi sint de Christo quod vivit, et Filius Dei est, et habitat per fidem in cordibus nostris, ipsum habere videamur. Quod eo proficit, ut securi simus de auxiliis ejus; quia non deserit nos, sed semper adest propter fidem suam, quam videt in nobis: quippe cum ideo Spiritus ejus, qui et Dei Patris est, detur nobis; ut vice ejus tutos praestet nos, si ei assentiamus, ut et occulta revelet; per quem utique ipsum in nobis habitare ambigere non debemus. Est enim hic alius paraclitus, inter quos personarum disantia est, non naturae; quia et de eo accipit, et a Deo procedit. In quibus enim naturae unitas est, invicem sui sunt; unde dicit Dominus: Omnia Patris mea sunt, et mea omnia Patris. Ambrosiaster, In Epistolam ad Ephesios, Caput III Source: Migne PL 17.384a-b

'To have Christ dwelling in the interior man by faith in your hearts.' 1  By this he seeks their greater firmness, that they not doubt but rather that they more believe that they have Christ dwelling in them, whom they do not see with these eyes, and as the Spirit is poured into them by the gift of God, so that they be certain that Christ lives and is the Son of God, and He dwells by faith in their hearts, let us also appear to have Him. Which profits because by that we are made confident of His help, since He does not abandon us, but He is always near on account of His faith, which He sees in us, for when His Spirit, who is of God the Father, is given to us, so His protection of us excels, if we assent to Him, so that He reveals hidden things, by which we will no longer doubt that He dwells in us. For there is another comforter, among them distinct in person and not by nature, since from God he is given who from God proceeds. 2 In which is the unity of nature of each one of them, whence the Lord says, 'Everything that is my Father's is mine, and what is mine is my Father's' 3 Ambrosiaster, Commentary On The Epistle of Saint Paul To The Ephesians, Chapter 3 1 Ephes 3.17 2 Jn 15.26 3 Jn 16.15
