Do you remember the parable of the weeds and the wheat? I have been meditating on the great truths that Jesus reveals to us in the parable about the nature of his bride the Church. I have been talking to some friends that are protestants who have joined or started "new" protestant 'congregations' (we refer to them as ecclesial communities since there can only be One Church). As I listen to them and some of their reasons for starting new 'communities', it reminds me of one of the main reasons that I became Catholic.
The reality of the Catholic Church is that it was founded by Christ and that it is perfect because the Holy Spirit makes it so despite our sins. I like to say that I joined the one and only perfect Church made for imperfect people. One main difference of those who remain in the Catholic Church from those who leave is that we understand that it will not be until the end of time that the weeds will be separated from the wheat.
We need to be humble and accept Christ's mercy and wisdom. Mercy is God's greatest attribute. It is how God shows us He loves us. Let's always strive to be the wheat in the Church by prayer and growing in holiness. May God give us the grace to turn weeds into wheat.
