Someone once said to me that he did not want to be Catholic because the Church was too concerned with rules and laws, and that Jesus did not want us to worry about obeying rules, He just wanted us to love Him. The contradiction in that idea was not apparent to my friend (even after I tried to help him see it). It does not take long if you read the gospels to see that Jesus never supported that kind of lawlessness. Today, however, in the gospel reading, Jesus gives us one of the clearest statements of how love for God is always associated with obedience to His commands. Yes, there are some (like my friend above) who behave as though Jesus said something entirely different.
Many think that Jesus said to his disciples: "If you love me, you will keep my commandments (at least most of them; or at least the ones that are convenient; or maybe just a couple that you happen to like; well, tell you what, just do your best and I'll overlook the rest)." Is that what Jesus said? Our Lord did say the first part: "If you love me, you will keep my commandments" but the last part in the parentheses, that was entirely made up (and we all know it). If we know this to be true, why do some live like they thought that the last part was what He really said?
We make excuses. That is the real reason, and we all know that just as well. We look at one of His commands and decide that we know better, or that it does not apply to us. That may be how we reason through it, but it is not right (and we all know that as well). There is no excuse, no doctrinal twisting, no turning a blind eye, that can change the fact that our Lord calls us to obey His commandments and says that if we do not, then we really do not love Him.
For those who know this and submit to it (even if they struggle with it), Jesus promises a great help. He knows that we are unable to obey Him on our own, and He says He will provide for us the very thing to help us to get through the struggle. It is as though our Lord said, "you have to obey Me, and if you are willing to do so, I will give you the means to do so: My Holy Spirit". Those who do not really want to obey will not take advantage of the Spirit and so, for them, the obedience is impossible. Yet, for those who are willing, the help of the Spirit is the means by which they can obey.
This means that the Holy Spirit of God is the very key to the faithful life. Did you obey God recently (I am sure you did), then you did it by the power of the Holy Spirit. Did you disobey God recently (admit it, you probably did), then you did it because you did not take advantage of the Helper that Jesus promised. He even said that the Spirit would be with us always (meaning especially in those times of temptation and trial) and that the world could not receive Him. The world does not accept the help of the Holy Spirit because the world does not want to obey God in the first place.
Finally, we must realize that the Holy Spirit is the very means by which we can make sure that our obedience stems from love for God and not merely from a sense of duty (which is good, but not a sufficiently holy obedience). This is why Christ says "if you love Me you will obey". Love and obedience go together hand in hand. They are two parts of one whole and for us to imagine that we can love God without obeying Him is a grave misunderstanding. Obedience without love is cold and superficial with no real commitment. Love without obedience is merely a sentimental feeling (and not true godly love). So, as our Lord said, "Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind; this is the first and greatest commandment". Let that always be our goal. In the Name ✠ of the Father, and of the Son, and of the Holy Ghost. Amen.
