For already some have turned aside after Satan.
(97) “Since the gospel is preached to us, it is Jesus Christ who holds out his scepter, and shews us that he wishes to be our king, and to take us for his people. When we have thus made profession of the gospel, if we do not persevere till the end, if it happen that we debauch ourselves in any way, not only do we refuse to be in obedience to the Son of God, but we give to Satan all mastery over us, and he will seize it, and we must be in his service in spite of our teeth. If this is dreadful and absolutely shocking, ought we not to be better advised than we have been to conceal ourselves under the wings of our God, and to suffer ourselves to be governed by him, till he renew us by his Holy Spirit in such a manner that we shall not be so giddy and foolish as we have been? For that purpose, let us consider that we must have our Lord Jesus Christ for our guide; for if we wish to be truly the people of God, the saying of the Prophet must be fulfilled in us, that the people shall walk, and David their king shall go before them. Let us always have his doctrine before our eyes, and let us follow him step by step, hearing his voice as that of our good Shepherd, (John 10:4).” — Fr. Ser.
