Interestingly, there are two sets of Laws that are to be found in the Pentateuch. The First being the simple and more direct words of God as commandments to the Israelites, namely the Ten Commandments. After that in a way God disassociated with the Israelites, and the working rules and regulations sometimes given by God through Moses, like the instructions for the building of the Ark of the Covenant and the Tabernacle, but mostly the other rules and regulations were given by Moses, among others the concession of divorce.
If one lived by imitation of God – i.e. in love, we do not require any other instructions, except the basic notion of what is good, bad, acceptable and not acceptable. That is what the Ten Commandments did. But when the Israelites showed they were not capable of the Law of Love, God had to prepare them to be able to Love like himself, and that is why all the other things (rules and commands came in play. Jesus takes us back to the Law of Love. He invites us to Love like Him, who is God, and this is possible, because He accomplished this in His humanity on the Cross.
Love know no bias, is equal and is for all. He that does not understand this, does not know love, or has rejected love, or rejected it by becoming self-serving. Jesus in today’s Gospel is inviting us on the right paths of Love – love everyone, even your enemies, and pray for everyone, even your enemies. Be welcoming of everyone, even people you are insecure about. This is the path of truth, and imitation of God. And when we imitate God, we proclaim God to be our Father.
