Following my last post on a sports theme, here is another of interest. There seems to be effort in the US to have a baseballer player declared a Saint. A Catholic filmmaker Richard Rossi feels a Cause should be started and he is gathering information for Church authorities. Roberto Clemente, a baseball player who died in 1972 in an aviation accident, is said to have lived a holy life while being one of the US's great sportsmen.
In the Church if a person or group of people are convinced of the holiness of an individual, they are free to try and work towards the opening of a Cause. They need the support of the local bishop who will examine the evidence to see if a Cause is possible. So Rossi is doing the right thing in compiling his evidence.
In the article above I note a little misunderstanding. It was noted that "the chances of the Church canonizing a layperson are not great". That is unwarranted and misleading. Being a layperson does not exclude anyone from glorification in the Church. Causes for laypeople can be more difficult because they may not have a religious order behind them, but the the chances of the Church canonising a layperson are as good as any other member of the Church.
Indeed sometimes it can be harder to get a Cause open for a priest or religious because even if people are convinced of the holiness of a person and the person's life confirms that belief, and even if miracles are being worked, if the bishop or superiors of the priest's/religious's diocese or congregation refuse to consider a Cause, there is little that can be done until the obstruction is removed. But then that might need to become another miracle for the candidate to work.
